Electronic Card Insulation Varnishes

Electronic board insulation varnishes are coating materials applied to circuit boards to protect the board and its components from corrosion and external environment. Chemicals, dust, extreme temperatures and humidity can damage electronic components, so protection is necessary to ensure efficient operation. In addition to protecting electronics from malfunction or damage, electronic board isolation varnishes also help electronic devices withstand harsh environments. Electronic card isolation varnishes protect electronic circuits from environmental pollutants while allowing moisture to escape.

Why Use Electronic Card Insulation Varnishes?

Electronic card isolation varnishes are used in the vast majority of electronic devices to provide the required combination of reliability and high performance. Electronic board insulation varnishes are typically applied onto a board circuit by painting or spraying. By coating the ends of electronic components, solder joints, exposed traces and other metallic areas and protecting them from corrosion, electronic board insulation varnishes materials extend the operating life of circuits.

Electronic Card Insulation Varnishes Features

Electronic board insulation varnishes are particularly resistant to environmental extremes, including alkyd-based compound, oils, water and most acids and alkalis. It retains its high dielectric strength even when wet and is therefore particularly adaptable for the insulation of electrical and electronic devices or components that can be operated in a very humid climate and at high temperatures. It provides general insulation of coils, transformers, motor windings and all-round protection against oxidation and atmospheric attack.
