Overview

4226A is a highlyinsulating varnishwith excellent arc and corona resistance. This dielectric coating is a low viscosity, 1-part coating that is easy to use and adheres well to many substrates.

Dielectric coatings like 4226A protect high voltage parts such as transformers, coils, motor windings, and various electric generator parts against arc,corona discharge, corrosion, and moisture fouling.

4226A is free of hazardous air pollutant solvents (HAPs) such as xylene and toluene.

For dielectric coating, see4228.For red insulating varnish, see4228A.
