Conductive greases for electronics efficiently lubricate moving parts, offer superior protection against corrosion and help ensure electrical continuity between irregular surfaces. However, such bridges cannot be used interchangeably with the wheel bearings of the vehicle. nuts, to prevent galling. White lithium grease also has another excellent ability to withstand extreme temperatures. Next is a study of anti-seize compounds-a project that anyone who has scarred their knuckles trying to free a seized bolt will appreciate. 8481 is a premium, carbon-filled, silicone-free electrically conductive grease. zero, when we switched to pure dielectric grease.In bolted or clamped connection will eventually fail. (Not all things that show silica that increases wear. Its thin metal base spreads very well and fills all the voids. Post Posted: Sun Jun 10, 2012 4:19 am . You can depend on them massively for extensive use. You absolutely DO NOT want a conductive grease in a connection as it will act as a direct short and probably blowing a circuit. Although it is neither dielectric nor conductive, it resists being washed-off and excels at fighting corrosion. terminal-to-post voltage drop. While that grease solved problems, it was Summary of Dielectric Grease Vs. Silicone Grease Conduct. sealing contaminants, moisture, and air out of connections. Also, Vaseline has a very low melting point compared to the dielectric grease which can withstand extreme temperatures. Although we did not test for this, conductive greases might also reduce signal strength in radio equipment; coaxial cables used in antenna connections, in particular, should be kept clean and dry. Dielectric grease, on the other hand, is a waterproof grease that repels moisture out of a connection. problems, I never use it in my installations. grease. beryllium, mica, silicone. Usability Bulb greases have specified significance compared to its competitor. Therefore, on top of lubricating and preventing corrosion, the grease also prevents fusing and arcing in terminals and electric connections. This medium thickness grease from Thomas and Betts is loaded with copper particles. Even at relatively high temperatures as water, rust and dust repellent, this grease acts like an invincible warrior. automotive applications, flooding with a For this round of testing, we repeated our static corrosion protocol (Winch Grease Corrosion Tests, PS, October 2016) using only a copper/solder pairing. And we could find no improvement in our tests. Now the question is, does dielectric grease have any substitute? contacts to select each channel, and the clear silicon grease (which replaced a of finely-powdered Silicone dielectric grease applications: One incorrect logic is the "dielectric" in "dielectric grease" means the push fit electrical connectors, or if I am unsure of metal to grease compatibility. Silicone-based greases may be at the top of your list for a variety of electrical connectors to be electrically insulated. (Explained)Continue. Conductive greases and anti-seize compounds have a suspended base metal high power, because most greases will carburize when subjected to an arc. 1-16 of 579 results for "conductive grease" RESULTS MG Chemicals - 8481-1 Premium Carbon Conductive Grease, 3 fl. Below are some of the excellent substrates for dielectric grease: The best substitute for dielectric grease is silicone-based grease. centered around dry connections that corroded, and around aluminum trunk cable 4.6 L vs 5.7 L Tundra: What to Pick & What to Avoid? Belleville washers. Even if the mechanical temperature is -45 to 450 degrees, synthetic grease can withstand this temperature. Who Makes Motorcraft Spark Plugs? Electrical resistivity is a measure of how well a material opposes the flow of electricity. To assures the insulator property of dielectric grease, we can perform a simple test with the help of a multimeter. How Often Should You Clean Your Air Fryer? If you follow the right procedure and use the right amount of dielectric grease then you can expect a great performance from it. Although dielectric grease and conductive grease both act as isolators, the main difference between the two is that conductive grease contains fine metal powders. I use it to lube stainless bolts and will be acceptable. Dielectric Grease Pros 1. Which grease should if I want better electrical conductivity? You can use them on the plastic surface. directly on high voltage CRT anode Vaseline conducts electricity: Melting Point: Very High . periods of time. On the other hand, it will not bleed current, so is a good choice for spark plug boots, multi-pin connectors, and thinly applied to antenna connections (wipe on, wipe off). Use of Dielectric Grease vs. White Lithium Grease In the waterproof grease class, we tested Green Grease from Omni Lubrican'ts, and Lanocote from Forespar. with several grease manufacturers, I switched to a GE 100% pure silicone the material compatible grease does not bridge insulation. completely wishful thinking, and the type of grease has virtually no impact on Dielectric grease, on the other hand, is suitable for places that do not necessarily require any conduction. They maintain a Synthetic greases are not sticky, they do not melt or roll, they do not evaporate with excess heat, they do not separate from the surface. It protects and prevents electronic components connectors from dust, dirt, rust, water and other troublesome substances. This excellent, Read More Can You Mix Red and Green Antifreeze? flooding F connectors that were directly exposed to snow or rain. Our testers concluded that the metals in these greases actually increased galvanic corrosion if there is seawater present. As you probably know, one actually almost never should use a conductive grease on electrical contacts, so that is actually good news. This leaves a fine metal exactly opposite claims, at least one notion or claim is wrong. How to Clean the Idle Air Control Valve on Toyota? In practice, the metal particles dont improve the electrical connection, but they can help shield against the moisture and air that lead corrosion. Theoretically, it is used in various types of electronic connections of a vehicle, such as light bulbs, spark plug buds and battery terminals, to provide additional protection. Conductive greases also have electrical conductivity and therefore can transfer current between two points, whereas dielectrics cannot; this is particularly important where corrosion protection and the ability of a compound to withstand applied voltages are necessary. Low-voltage generally would include consideration of This grease isnt sticky at all, and its transparent. However, whenever youre dealing with light bulbs and their connections, bulb greases should be preferably used. Dielectric grease will reduce corrosion but it is not conductive. If you want effective grease at a high and wide temperature you can choose silicone-based grease. this claim is in the word "dielectric" used in the name. temperatures. Silicone grease has been around for a long time. simply carried most of the suspended powder away. The The finely powdered metal is suspended by insulating grease, so it does not conduct. We used that grease without incident for many years If so, what are they? Any heat will cause Vaseline to run and eventually dry out over time. I use Noalox on clamped aluminum slip joints in antennas because it is generally less off significantly. silicone greases should be used. between battery terminals and an automotive battery. (Super Lube Synthetic Grease, though not lab tested, is included in the table for price comparison). The main difference between dielectric Grease and White Lithium Grease is their compositions, properties, and area of usage. You can use white-lithium grease and many others. this case, both are wrong. Although there are some similarities between vaseline and dielectric grease, there are some differences between them. It is somewhat messy, but tenacious. Dielectric grease is an entirety of non-conductive grease. They In the waterproof grease class, we tested Green Grease from Omni Lubricants, and Lanocote from Forespar. This article discusses the substitutes of the most suitable dielectric grease possible. One doesnt have to be a genius to know this. Conductive greases should These greases are also bad choice for multi-pin connectors, where they might create a short circuit. Bulb greases use silicone-based features, and thats why they are typed under silicone greases. Dielectric grease is not a conductive material, it is an insulator. Most brands or types liquefy at around It works like a gel with any surface, not just metal, creating strong insulation. 1. For sensitive circuits where minor bleeding of current is problematic, dielectric grease is recommended. This is obviously wrong for several Its a good sign if I cant easily wash it off because its an assurance that it continues to protect in wet surroundings. I suspect Corrosion failure rate dropped significantly, almost to Because it is non-conductive, it does not allow the flow of electrical current. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[320,50],'toolsmechanism_com-leader-1','ezslot_6',150,'0','0'])};__ez_fad_position('div-gpt-ad-toolsmechanism_com-leader-1-0');Bulb grease is a lubricant used for repelling corrosion and oxidation on light bulbs. The two could be used interchangeably. This may create an impedance bump at very high frequencies, the However, this grease is present in various forms with different features. A standout performer in our waterproof grease and winch grease testing, we have used this product from Omni Lubricates on terminals for decades. fingerprint bridges the spark plug insulator. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); You have entered an incorrect email address! boots on race engines and in high voltage connectors. powder. Being a grease with high thermal conductivity and relatively low instability, it has quite good fluidity. reasons, most predominantly because of voltages and currents involved. It has a thickener called silica, but this grease isnt sticky when a greased part comes in contact with another body. It was demonstrably less effective than Green Grease in our tests. In other words, if you need lubricants with silicone-based features, then bulb grease is worth choosing. This grease is used across all industries. It lubricates, reduces contact resistance, repels moisture and inhibits corrosion. The cable I also use silicone dielectric grease for battery terminal green or red petroleum grease) lubed the contacts Petroleum grease (Vaseline) was recommended (and was apparently used) on low I continue to use silicone dielectric grease today. You want something that will seal out water and air, preventing both galvanic and general corrosion. On the other hand, vaseline can be used as a suitable option to prevent the erosion of the same ingredients. Generally, greases are made with oil as a base in addition to a thickening agent that . force excess grease out of the area between the heatsink and the resistor tab. Bulb grease isnt the only type of dielectric grease that you can use for lubricating electrical connectors. Synthetic grease is a type of lubricant that does not contain any petroleum. It acts as a perfect insulator of your car connectors so that your car and its various parts are free from damage like dust, water etc. Notwithstanding, the thickener popularly available in bulb grease is silica. It also performs well in decaying areas. Non-conductive or dielectric grease. Post subject: Dielectric Grease vs Conductive Grease. pressure. insulators, especially in the presence of moisture. applications. or volume controls, cadmium, zinc, silver, or gold Meanwhile, silicone greases have outstanding qualities that make them stand out among other dielectric greases. I feel like they help, but I'm not sure if that is true. Instead, it maintains the intensity. Ill use it on my boats that are frequently exposed to water. The use of specialized conductive grease using aluminium or copper blocks on different types of surfaces does not result in such an improvement. Dielectric Grease vs Vaseline Dielectric means that it does not conduct electricity, so it would seem counterintuitive for use in an electrical connection. Both dielectric grease and "conductive" greases (anti-seize) are insulators. grease as a contact protectant. insulating grease, and so the grease still insulates the connection. performance, as a properly selected metallic powder grease (conductive grease). Silicone and low voltage signal level module contacts. Weve even used these on our test boats for electrical connections, without any issues. time, and actually makes a good fire starter. grease should only be used to insulate. Protects Plastics If you need to carry a lot of load over rough terrain, the performance of the Toyota, Read More 4.6 L vs 5.7 L Tundra: What to Pick & What to Avoid?Continue, Have you ever wondered who makes Motorcraft spark plugs? Electrical conductors should not be coated with dielectric grease prior to being mated. field failures from bad electrical contact connections in new modular Literally, one can decipher the purpose of bulb greases; they are for preserving the luster of light projectors, connections, and encasements, unlike its comparison that serves generic purposes. Grease, when used in automobiles, acts as a lubricant that possesses stability, high dropping point, and wear-resistant properties. Silicone Dielectric Grease (and lubricant) is a low viscosity grease. Plus it can give you the advantage of being one of the best electrical insulators. Bottom line: Recommended for general use. enough to reliably reduce voltage drop across clamped connections. These are usually made with lithium soap from fatty acids. Never use or allow a It was used in the following Use this on GPS cables, multi-pin connectors, and spark plugs. Dielectric grease is a very necessary and popular part of garages not only in our country but all over the world. Is it possible to prove whether dielectric grease has the property of electrical conductivity or not? Conductive greases should specifically match materials being clamped. MG Chemicals 846 Carbon Conductive Grease is a carbon-filled, electrically conductive grease. Nevertheless, the constituents in bulb grease to withstand high temperatures make them highly specified for lubricating bulbs. Bulb grease doesnt sway divergent or convergent rays of light. The word No-Ox-ID does has no metals. Some posts may contain affiliate links. quality over time while dielectric greases will isolate connections because What Are The Substitutes of Shredder Oil? If you have any doubts about this, then through this discussion you will get a good idea about the substitute for dielectric grease. The right question should be, can I use silicone grease instead of any other dielectric grease because silicone grease is an example of dielectric grease. Conductive grease has better thermal stability than dielectric grease which makes it useful up to 400F (204C). Connection enhancement from embedded metal powder is very minor, if it exists at at 1%, is better than bare metal-on-metal. Usually, a one wire sensor like most O2 sensors, you want to use conductive grease and not dielectric, as the sensor uses the threaded portion of the sensor to get a good source to ground. Dielectric grease is not just any type of coolant or oil, it is one of the many lubricants available in the market. Therefore, the bulb grease is called for in cases that warrant shielding an electrical connection in a way that does not inhibit the flow of charges. I also use directly on that "conductive" greases and anti-seize greases include some amount of finely-powdered metal. Some call pure 2. failure. This means conductive grease is application specific. The important physical characteristic is that any grease must have low enough Pros of Dielectric Grease Dielectric grease has a lot of advantages, especially when used correctly. What Are The Substitutes of Dielectric Grease? shields were aluminum, the trunk center conductors cables were copper clad Drop cables were aluminum shields and connectors, with copper clad In single high voltage connections, such as spark plug boots or other high Save my name, email, and website in this browser for the next time I comment. Our test used the same protocol as our most recent static corrosion test (Winch Grease Corrosion Tests, PS, October 2016), using only a copper/solder pairing. It can be a good substitute for long-term solutions for the favourable nature. My first experience with silicone grease was in the 1960's as a lubricant in However, because silicone grease needs constant application, there is a need to apply the lubricant on continuous bases consistently. Using too much dense grease, like thick heatsink compound, greatly increased Which Subaru Outback Years to Avoid and Why? extend life. that "conductive" greases and anti-seize greases include some amount Check out the constituents in bulb greases in the next sub-topic. resistant, and be stable enough to remain in place as a protectant against sparkplug or ignition fault indications. The notable difference between the two solutions is the preservative power of dielectric grease. Such as: Compared to dielectric grease, silicone-based grease replaces the best option as waterproofing. on insulators or insulation, seriously degrades high voltage hold off. specialized conductive greases. There is essentially no difference between Permatex Dielectric Tune Up Grease the interface to prevent galling or conductive grease Both dielectric and conductive grease are recommended by equipment manufacturers and marine professionals, so we tested both. metal. television tuners, where channel coil packs or "strips" were mounted in a rotary expensive to apply to tens of thousands of fittings. metalized grease around HV connections. Dielectric grease is useful when you need to prevent corrosion from taking place on equipment that has a metal or non-conductive surface, whereas conductive grease can be applied to any type of metal for the purpose of increasing its electrical conductivity. Our conductive grease group included No-Alox from Ideal Industries, No-Ox-Id made by Sachem, and Kopr-Shield made by Thomas and Betts. (galvanized), lead-to-lead, stainless-to-copper, and stainless-to-aluminum We suspected this approach to fighting corrosion might be a problem in a saltwater environment, but we didnt realize the effect would be so obvious. by roughing the heatsink with ~300 grit paper. Author Topic: opinion on conductive vs dielectric grease for contacts (Read 1256 times) 0 Members and 1 Guest are viewing this topic. I use it in Weve used this on everything from battery posts to GPS cables. Both types of lubricants are made from similar compounds, but it is possible for one or both of these compounds to become conductive if they are exposed to an electrical current. We have reviewed several conductive greases (see Marine Wiring: Are the Pricey Options Worth the Cost? does not conduct. Creates Seal Dielectric grease offers a strong seal for metal surfaces. In fact, most switch vendors advise using dielectric grease. However, Vaseline is not a professional grease that you can apply like dielectric grease. Forums also claim dielectric grease This 100% pure silicone dielectric grease Our dip into the world of greases is not over. The test period was 14 days and the test fluid was 30 percent seawater; a combination of environmental stresses, which, based on industry experience, should mimic 5-10 years of normal use in a damp environment. arc paths through the grease. Electrical lights and electrical connectors use bulb greases for lubrication because the silicone content is a good oxidation repellant. (Answer Explained). Brake Grease on Back of Pads | All You Should Know, Every locomotive part in automobiles and industrial machines needs lubrication. Very similar to No-Ox-Id Special A, weve used Forespars Lanocote for decades with no failures. to the heatsink with a stack of The change in You can use synthetic grease as a great substitute for dielectric grease. It was also commonly used as a lubricant and protectant on turret-type The connections were a mix of copper, aluminum, and steel. Indeed, thats why they are vastly used e needs and the weather at a point in time. Pour point is an engineering evaluation of the temperature that a material will migrate (run) of its own accord with gravity only. The finely powdered metal is suspended by insulating grease, so it does In addition, this type of grease doesnt impede the floatation of electrons in the electrical connection that you might be preventing against rust. To determine if conductivity was impaired or improved using any of the products, we measured temperature rise in a slightly over-loaded extension cord plug (25 amps in a 15-amp plug), using a fresh female part for each test. What Are Equivalent To Subaru Super Coolant? problem's effect on the system being entirely dependent on the length of the This is why marine electronic equipment vendors traditionally recommend dielectric grease-it is more forgiving. Can a grease flow juiceCan I brush my teeth with that black stuff? Moreover, our tests clearly showed that in the presence of seawater these products can increase the risk of damage due to galvanic corrosion. 2. It provides excellent protection against wear, friction, corrosion and rust. Dielectric grease, on the other hand, is suitable for places that do not necessarily require any conduction. There are many cases where lubricating contacts accelerates breakdown voltages of air paths or surface path resistances of insulators Dielectric grease is a thick gel that offers premium protection against moisture, corrosion, and electrical arcing. There are some cases where very high Practical Sailor, December 2010), testing their ability to protect wires and terminals for extended periods in a salt spray chamber, but we did not look specifically at the claims made by some non-conductive greases. White lithium grease also has another excellent ability to withstand extreme temperatures. When the layer was thinned to a light "wipe" of grease, thermal resistance fell Greece removes most of the suspended powder. Articles claim sparkplug threads are insulated by anti-seize, causing Are the benefits of tinfoil hats real and should I wear one?All of these questi. Dielectric grease is incomparable to preventing corrosion and increasing the efficiency of electronics parts. insulation. The suspended metal powder does lower the voltage breakdown of any Dielectric Grease Vaseline; Usage: Dielectric Grease is majorly used for sealing and protecting the electric components. Conductive grease is usually made of carbon particles and other conductive materials. Features and Benefits Excellent corrosion resistance RoHS and REACH compliant Lubricates moving parts Prevents pitting and hotspots Wide operating temperature NEVER use conductive greases on It is not necessary to use it but its use gives extra protection to your car and its parts and increases the lifetime. viscosity to push out of the way at contact points, be water or liquid This grease isnt sticky at all, and its transparent. Neither is true. switch or relay manufacturer suggests. During the course of our multi-part reporting on greases, several readers asked if a conductive grease would be better for these connections. the real problem was anti-seize contaminated the plug insulator. 5 Major Differences between Bulb Grease and Dielectric Grease: 1. Also, if you want to include a product from SuperLube, it should have been their Anti-corrosion & Connector Gel product instead of the silicone grease. benefit when coating human skin, it is a serious problem with connector Similarly, there must be some differences between dielectric grease and its substitutes. effective at preserving connections as "conductive" grease, and will not harm It also performs well in decaying areas. While most greases emphasize lubrication, conductive greases focus on corrosion protection by keeping out water and oxygen. As a systems engineer, I was both improve insulation and preserve electrical connections. However, if you do not find an option as a substitute for dielectric grease, you can use vaseline temporarily. They are an excellent repellant of water. Generally a light coating or wipe is all that The Electrical Conductivity of Dielectric Grease As we have mentioned earlier, dielectric grease does not conduct any amount of electricity but acts as a very good insulator instead. The less noble zinc dust in No-Alox might act like a propeller anode and provide sacrificial protection in aluminum joints. screw torque as a factor in results. However, always try to use direct dielectric grease. The primary enemy of a good connection is corrosion, so anything that excludes water and oxygen from the connection is beneficial. Hence, it prevents the flow of current. (Answer Explained), 75w85 Vs. 75w90 Motor Oil: The Head-to-Head Comparison, Can I Use 10W40 Instead of 5W30? meaningfuly alter performance, but they do indicate a potential problem.). We looked at three different conductive that claim to protect electrical connections. If you cant find a retirement, use a substitute, otherwise not. insulation or other things that can act like wicks, petroleum jelly is not the In reality even conductive greases and joint compounds behave to some degree as insulators, with resistance of more than a million of ohms per millimeter. liberal amounts on ground connections, to inhibit corrosion on stainless-to-zinc In our view, the makers claim that it copper plates the surfaces it joins doesnt make sense in a marine system, where the wires and connections are already copper, or pre-tinned copper. The test coupons were immersed in the heated salt bath for 14 days. switched" and have any chance of arcing. power antenna installations years ago. Later, RCA, Motorola, and Magnavox, facing 100 degrees F, just above human body temperature. While people report using it without Belvoir Media Group, LLC. It works best in plastics and savers compared to other metals; It takes care of the vehicles electrical connectors and parts by withstanding extreme temperatures; Protects against various types of catastrophic events such as fires; Even if applied to high voltage areas, it fights efficiently. The initial Finally, some regular grease conducts electricity while dielectric grease is a non-conductor. A second petroleum jelly issue is Vaseline's release of flammable vapor, Some claim dielectric grease is conductive or abrasive, containing You can often hear that you should put dielectric grease on battery terminals. For more details, see How We Tested. However, buy from a manufacturer that offers the best services in the industry and check the elements in the bulb grease. Here is a test using a 35-watt dissipation resistor. connections, I have no opinion if conductive greases help or are necessary. This may be the best option for you to lubricate different vehicle parts. Silicone-based grease serves as one of the alternatives to water resistance. All of these problems were eliminated by "non-conductive" silicone grease. The grease However, it actually accelerated corrosion on the copper and solder test samples, which were significantly damaged. Its main use is providing protection from moisture by creating an airtight seal moving parts which means if you apply it correctly it will not migrate. Dielectric greases dont consist of grounded metal as their granule; likewise, the bulb doesnt. record turntables. Rotating the turret moved different channel strips over stationary Meanwhile, silicone greases have outstanding qualities that make them stand out among other dielectric greases. The die-electric or non-conductive material acts as a control gate or valve to the applied current. This time we elevated the temperature 140F, as is typically done for engine coolant testing, both to accelerate corrosion and to mimic a connection that is running warm. In my tests, it appeared the grease Offline: TBI Slant 6: Joined: Wed Apr 25, 2007 9:16 pm Posts: 100 Location: Tucson, AZ Car Model: So, I'm trying to secure my grounds a little better, but I'm confused about the purposes of different electrical greases: . In conductive environments, such as water, unlubricated connectors experience current leakage which can result in short circuits. Underwater electronic light uses this to maintain the intensity of the light generated from the electric bulb and prevent them from corroding simultaneously. all, and unless you match the grease to the connector material, risk of Testers noted heavy oxide coating on the solder sample in our test. Conductive grease can be used to lube electrical connections or as a corrosion inhibitor for metals. As a result, people who work with electricity should use the dielectric grease whereas people who want to create a lubricant effect can use the silicone grease.
