Silicone Conformal Coatings and their use in Electronics

A silicone conformal coating is normally applied as a thin layer across the surface of Printed Circuit Boards (PCB), covering all components and delicate wiring. To facilitate efficient functioning of PCBs which are exposed to harsh environmental working conditions in critical applications, it is necessary to protect them by applying such coatings.

Our Silicone based conformal coatings have following features:

• 1. Low Viscosity : Facilitates flow around, under and over the components without leaving areas exposed to the atmosphere, especially on sharp edges.
• 2. Good Adhesion : Maintains good adhesion to all the component substrates, be unaffected by changes.
• 3. Good Chemical Resistance : Protects the PCBs and the components from moisture, chemicals and contaminants.
• 4. Excellent Temperature Resistance : Withstands heat over a wide temperature range

Most of our silicone conformal coatings are transparent and employ both cure systems : moisture (Tin) cure and heat (Platinum) cure.
