Protective Coatings


Have a look at our savings on affordable protective coatings (made by MG Chemicals) for your circuit board projects. We have liquid tin; super corona dope; red insulating varnish; as well as urethane, silicone, and clear acrylic lacquer conformal coatings. These conformal coatings are durable, long-lasting, and protect against static discharge, thus safeguarding and insulating electrical and electronic components and assemblies — e.g. generators, motors, transformers, relays, and solenoid coils.
