Bertech's masking discs are available in a variety of shapes, sizes and materials. They are made from high temperature Polyimide film, Polyester and crepe papers with adhesive backings. We specialize in automotive, electronics and Industrial applications. They are used for masking during solder wave processing in the Electronic industry and powder coating and painting in industrial applications. Solder Wave Tapes and Solder Wave Discs or Dots are made of crepe paper with an adhesive backing.
High Temperature Masking Discs, also known as Polyimide Discs, are primarily used in circuit board production, wave soldering and other applications. They are made from 1 mil thick polyimide film with 1.5 mil of silicone adhesive which does not leave any residue. Polyimide Masking Discs can withstand temperatures of up to 500°F/260°C. They are packaged in a 3" core.
Applications: High temperature masking, Insulation on Transformers, Motors and Coils, Protection of circuit board during wave solder and Solar Panels
Conformal Coating Discs are made of 1 mil polyester film with 2 mil mustard colored rubber resin adhesive. The Conformal Coating Masking 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.
Applications: Conformal Coating, Powder Coating of switches and control panels and Paint Stripping.
Green Masking Discs, also known as Powder Coating Masking Discs, are made of 2 mil thick polyester film with 1.5 mil thick silicone adhesive. They can withstand temperatures of up to 400°F/204°C. Green Masking Discs are extremely economical and can be removed cleanly without leaving any adhesive residue. The discs are on a clear, slit back liner for easy removal. They are packaged in a 3" core.
Applications: Anodizing, Plating, Powder Coating, Solder Wave Processing.
Solder Wave Discs are made of 4 mil thick creped back paper with rubber adhesive. They can withstand 5 to 8 seconds of solder wave exposure up to 510°F (266°C) without adhesive transfer. Solder Wave Masking Discs can be removed cleanly without leaving any residue.
Applications: Anodizing, Plating, Powder Coating, Protection of circuit board during wave solder Process..
