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.
