4228A – Red Insulating Varnish

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.

  • Material Group I (CTI ≥600 V, PLC=0)
  • Excellent dielectric properties
  • Fast dry time
  • HAPs-free
  • Adheres well to metals, glass and many plastics
  • Provides excellent protection against moisture

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.
