Masking Dots are made of high temperature polyimide film. which are used in masking of circuit boards during wave soldering or other electronic manufacturing processes. It also can be used in powder coating, automotive and transformer manufacturing.
Polyimide masking discs have high dielectric strength. Polyimide masking discs offers excellent performance in electrical and thermal insulation. Polyimide masking discs have 1.2~1.5 mil of silicon adhesive which does not leave any residue. It can withstand temperature up to 280?. High Temperature Masking Discs are made of polyimide film with 1.5 mil of Silicone adhesive which does not leave any residue. They can withstand temperatures of up to 500°F/(260°C). These masking discs have high dielectric strength and offer excellent performance in electrical and thermal insulation.
