WBP / WBPs Aquacoat Plus

In Stock

Aquacoat Plus is a clear transparent water based conformal coating, based on polymeric materials which has been specifically formulated for the protection of electronic circuitry. It offers an excellent blend of both physical and electrical properties whilst eliminating the need for extraction and other precautions associated with the application of conventional solvent based conformal coatings. Aquacoat Plus is non-flammable and contains very low levels of VOC’s. Aquacoat Plus is available in two formulations. WBP is our standard material for use in dipping applications, whilst WBPS (Sprayable) is a lower viscosity product formulated for hand spraying equipment. Both variants have a UV trace for ease of inspection. For full product details including test results please refer to the TDS below.
