With the right additions, petrolatum compounds give excellent corrosion and water resistance. Petrolatum compounds are also translucent, allowing the technician to analyze them visually. Petrolatum lubricants can drip at high temperatures, although they keep their consistency well at low temperatures. What I have found to work even better is to apply conductive grease on an electrical connection, wipe off excess grease, and seal the connection with a generous amount of dielectric grease. This keeps the conductive grease from flowing to unintended areas.
The best dielectric connector grease for resistance to water and salt water – the product in this list that has the best water resistance properties. Eco-Friendly Options: There are greases available that are more environmentally friendly, made with biodegradable components. These options are effective in preventing corrosion and are a good choice for those looking to reduce their environmental footprint. Why not take a look at our article about the ‘ Facts & Myths of Electrical Connector Lubricants‘…some interesting stuff on there! Such as:Safety First: Ensure the vehicle is turned off and the keys are removed. Wear protective gloves and eyewear. Myth: Any Grease Will Do: Fact: Not all types of grease are suitable for battery terminals. Some types, like petroleum-based grease, may not perform well under high temperatures, while others like dielectric grease are specifically designed for electrical applications.
The best outcome is at the bottom. By roughing up the heatsink with 300 grit paper, all greases were tested in “scuffed” circumstances. Despite its advaantages, conductive grease can cause electrical hazard if it gets to the wrong places. For instance, the grease will cause a short circuit when it gets between live and neutral/ground in AC applications or positive (+) and negative (-) in DC applications. Regular application of grease can significantly extend the lifespan of your car’s battery. By preventing corrosion and ensuring good conductivity, grease reduces the strain on the battery, allowing it to perform efficiently for longer periods. The products discussed below are suitable for electronic/electrical applications and data connections – both digital and analogue.
Features & Benefits
Most people would not recognize dielectric grease from regular grease, much less explain how the two types of grease are different. Many drivers confuse the two or assume they are interchangeable. Both dielectric and regular grease have similar and different ingredients that make them unique but define the role each plays as a lubricant and protectant. Over several years, dielectric grease can start to melt silicone rubber. However, you shouldn’t use it on these surfaces in the first place. This type is infused with copper particles and is known for its excellent heat resistance and conductivity. It’s often used in high-performance or heavy-duty vehicles. Completely flooding the connector is totally acceptable in radio frequency low power installations, particularly at low frequencies and/or when the connector has very little air gap. Flooding a connector at high power is not recommended since most greases will carburize when exposed to an arc. Grease lowers the dielectric constant of the connector by changing the dielectric constant. The problem’s effect on the system is totally reliant on the duration of the hump in electrical degrees and the quantity of the bump. (Not everything that appears on a TDR affects performance, but it does signal a potential issue.) Climate Considerations: In hotter climates, a grease that can withstand high temperatures without melting, such as white lithium grease, is preferable. In colder or more humid climates, dielectric grease might be a better option due to its moisture resistance.
Our greases are the ideal option for easily compensating for voids within assemblies. This makes them a perfect solution for use in devices that have issues with flatness or coplanarity.The ‘go to’ connector lubricant for the majority of customers – widely used and the most cost effective product. Concerned that a dielectric connector grease will increase impedance across your connector? It will not. A quality dielectric lubricant/grease will not interfere with conductivity: It is not, however, a traditional lubricant. You cannot use it to grease bearings, joints, hinges, or other moving parts. For jobs like that, you need to get lubricating grease. Where to Apply Dielectric Grease? This silicone-based grease is unique because it’s non-conductive. It’s used to protect the electrical connections from moisture and prevent corrosion. It’s particularly useful in areas with high humidity or in vehicles that are frequently exposed to wet conditions.
