Urethane Conformal Coating
4223

Ideal for extreme chemical conditions. Urethane conformal coating is a durable finish product that provides a protective coating for printed circuit boards against moisture, corrosion, and thermal shock. It protects and insulates electrical and electronic components and assemblies, including generators, motors, transformers, relays, and solenoid coils. For spraying, liquid can be thinned using M.G. Thinner Cleaner. Thin up to one half part thinner to one part coating.

  • Fungicidal
  • Fast drying-units can be handled in 30 minutes
  • Apply by dip, brush or spray
  • Excellent chemical resistance
  • Oil and moisture resistant
  • Excellent for coating circuit boards
  • UV indicator for quality inspection
  • Superior abrasion resistance
  • Excellent adhesion
  • Good flexibility
  • Can be thinned to desired viscosity
