4228A is an easy-to-use, HAPs-free, 1-part, low-viscosity insulating varnish that cures at room temperature and adheres well to many substrates including metals, glass and most plastics. This varnish insulates high-voltage parts such as motor windings and transformer coils against arcing and discharge as well as protects metals from corrosion.

The coating’s distinct red color helps operators easily inspect coating coverage; however, for a clearcoat option, consider the 4226A. For insulation class H protection, consider our 4228.
