Conformal Coating Discs are made of 1 mil polyester film with 1.5 mil rubber resin adhesive. They offer high temperature resistance needed in the conformal coating process. These discs are silicone free, therefore they do not leave any silicone shadow. Many components and printed circuit board locations must remain uncoated and the purpose of the conformal coating masking discs is to prevent migration of the conformal coatings into components.They can withstand temperatures of up to 325ºF. Conformal Coating Discs offer the perfect solution to ensure areas for use as connector locations or insertion areas for interchangeable devices remain free of the protective coating.

Custom sizes are available upon request.

Applications: Electronic Circuit Board Assembly, Powder Coating of Switches and Control Panels, Conformal Coating Process, and Wave Soldering
