Three Anti-corrosion Glue

Three-Proof Coating for PCBs, also known as conformal coating or circuit board protective coating, is applied to the surface of printed circuit boards (PCBs) to form a protective film. This film helps protect electronic assemblies against moisture, dust, corrosive contaminants, and other environmental factors that can affect electrical performance and reliability.

Depending on the coating formulation and application conditions, three-proof coating can help reduce the risk of corrosion, surface contamination, fungal growth, and electrical short circuits in demanding environments. It is used to protect rigid and flexible circuit boards, electronic control systems, and other sensitive electronic components in industrial, automotive, household, and aerospace-related applications.
