Copper allows these lubricants to conduct electricity, while graphite gives them good chemical and corrosion resistance. Also known as thread lubricants, antiseize lubricants prevent threaded fasteners and close-fitting parts from locking together due to corrosion, contamination, or heat.

Loctite® C5-A Copper-Based Anti-Seize lubricants can be used with salt water and petroleum-based chemicals.

Dielectric strength measures the maximum voltage a lubricant can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.

Electrical resistivity is a measure of how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.
