Features
■ Polyester films offer excellent thermal, abrasion, and chemical resistance while maintaining their flexibility.
■ Silicone adhesives offer high heat resistance compared to many rubber and acrylic adhesives, reducing failure due to softening, oozing and adhesive transfer.
■ Silicone adhesives adhere well to tough-to-stick-to surfaces like silicone liners and fixtures coated with mold release.
■ Removes cleanly from stainless steel, anodized aluminum and glass after a 5 hour. bake cycle at 350°F (177°C).
■ Variety of tape thicknesses offered allows uses for multiple applications.
■ Application Ideas
■ Splicing of silicone treated webs.
■ Masking parts for powder coat painting
■ Holding parts or sealing vacuum bags during processing
■ Masking edges of overlap seams in metal bonding process where excess adhesive flows onto tape. Minimizes clean-up on tape removal.
