What Is Dielectric Grease?
You can identify dielectric grease by its physical properties, which make it unique from other lubricants:
- Firstly, dielectric grease is electrically insulating, meaning it cannot conduct an electricity current;
- Also, this water-resistant lubricant keeps moisture out of electrical connections. As a result, it lowers the possibility of corrosion, which leads to costly repairs;
- Dielectric grease is also non-conductive, non-curing, and silicone-based;
Dielectric grease is made up of several ingredients, including silicone oil, a thickening agent, and a softener. There are two types of dielectric grease- silicone-based and synthetic.
Silicone-based dielectric greases are composed of around 70% silicone oil, which makes them useful for high-heat applications, such as spark plug boots, ignition parts, and other engine applications.
Synthetic dielectric grease, on the other hand, is made up of a combination of several synthetic chemicals that provide lubrication while offering electrical insulation. Synthetic dielectric grease is also known for working on a wider range of temperatures than silicone-based grease.
As with any lubricant, there are precautions to take when handling dielectric grease.
Firstly, it is important to know that dielectric grease is not suitable for use with bearings and other moving parts because it doesn’t provide enough lubrication as and when required.
Secondly, using too much dielectric grease can lead to an increase in temperatures. In it turn, it leads to a spike in resistance. As a result, this leads to an electrical breakdown. Thirdly, when applying dielectric grease, ensure that it doesn’t affect other parts of the equipment, such as sensors, switches, or cooling systems.
Lastly, we should remember that dielectric grease should be used to coat the surface of the materials and not be applied like a paste. This will help to prevent it from building up and attracting dust and other particles.
What Does Dielectric Grease Do?
Dielectric grease is a versatile and essential product used in various industries and applications, from automotive maintenance to electronics. This non-conductive lubricant serves a specific and crucial purpose – to protect electrical connections and components from moisture, corrosion, and other environmental factors.
