4226A is a highly insulating varnish with 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, see 4228. For red insulating varnish, see 4228A. Features & Benefits High dielectric strength Maintains dielectric protection under conditions of high humidity and high temperature Excellent finish – tough, flexible, glossy, and durable transparent coat Adheres to metals, glass, and most common plastics HAPs-free solvent system (no xylene, toluene, and MEK)
