Acrylic Lacquer Conformal Coating
419B
Acrylic Conformal Coating is a durable finish product that provides
an all round 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. Also available in a
micro
tip pen
format.

Liquid in contact with eyes may cause permanent eye damage.
May cause skin irritation with pain and stinging, especially if skin is abraded.
Solvents may cause respiratory tract irritation, headache, and possible dizziness.
May cause respiratory and digestive tract irritation.
Prolonged and repeated exposure may cause dermatitis, defatting of the skin, liver and kidney
damage, and adverse central nervous system effects.
