Epoxy Conformal Coating
CAS Number: 25068-38-6
Epoxy conformal coating provides the hardest and most chemically resistant protective film among standard conformal coating types, offering outstanding protection in aggressive chemical and abrasive environments. Its two-component system cures to a rigid, impermeable film with excellent adhesion to FR4, ceramics, and metal substrates. It is particularly suited for downhole oil and gas electronics and chemical processing instrumentation.
