A high temperature masking tape is a single-sided polyester masking tape with silicone adhesive... BiTape 983V is the powder coating masking tape rated for sustained service up to 480°F — typical powder coating cure ovens, e-coat ovens and flashbreaker work on cured epoxy coatings — with the silicone adhesive bonding reliably to silicone-treated surfaces, mold release fixtures and other tough-to-stick substrates.

The silicone adhesive system is engineered for two reasons. First, it withstands sustained heat up to 480°F without softening, oozing or transferring residue — rubber adhesives typically fail at 250-300 °F and acrylic adhesives are not suited to silicone-treated substrates. Second, silicone bonds well to tough-to-stick substrates: silicone liners, mold release fixtures and other low surface energy materials commonly found in composite tooling, electronics encapsulation and powder coating masking tape production lines. The trade-off is that silicone masking tape is more expensive than rubber — specify high temperature masking tape only when the application demands silicone properties.

BiTape 983V high temperature masking tape is single sided — adhesive on one face only — engineered for temporary masking, holding and splicing during high-temperature finishing operations. It is NOT a double-coated tape and is NOT intended for permanent bonding. For double-sided industrial bonding specify BiTape acrylic foam tape (510T, 901G, 912N) or PE foam tape (485N, 4203B, 4500B). For thin double-sided tissue or PET tape specify the BiTape thin double sided tape range (0960B, 0962B, 0965T).

BiTape 983V high temperature masking tape is rated for sustained service up to 248°C / 480°F. This window covers the typical cure ovens of powder coating masking tape applications (typically 350-400°F), flashbreaker on cured epoxy coatings, e-coat ovens and vacuum bag sealing during composite cure cycles. The silicone masking tape adhesive resists the softening, oozing and adhesive transfer that disqualify standard rubber-based masking tapes at these temperatures.

BiTape high temperature masking tape is specified for metal finishing (powder coating, anodizing, e-coat lines), automotive (paint line masking, e-coat ovens, flashbreaker on cured coatings), composites (vacuum bag sealing, mold release surfaces, prepreg holding), electronics (component masking on surfaces with silicone liners) and general metallurgy where corrosive chemical processes and temperatures up to 400 °F require a polyester silicone masking tape.

The masked surface must be dry, clean and free of dust, grease or adhesive residue. Apply firm pressure across the full contact area for a sharp, defined paint line. The silicone adhesive bonds well to tough-to-stick substrates such as silicone liners and mold release fixtures, but standard substrates (metal, glass, painted surfaces) should still be wiped clean before tape application. Run a small adhesion test on porous or unusual substrates before full deployment.

The silicone masking tape adhesive resists the softening, 1/2 in, 3/4 in, 1 in and 2 in on 72 yd rolls. Custom widths and die-cut shapes on request — particularly useful for high-volume powder coating, anodizing or e-coat masking lines that require precise geometry. Shelf life 24 months from date of manufacture, stored at 60-85 °F and 40-60 % relative humidity.
