Spray these abrasion- and wear-resistant coatings on motor winding wire, transformers, and other metal electrical parts to protect them from oils, chemicals, and moisture. They are solvent based, so they dry quickly. Choose a varnish with a dielectric strength that’s greater than the voltage of the electrical equipment it protects.

Clear varnish leaves a transparent film so components can be inspected. Red and green varnish stand out for identification when used to coat wire.
