Glass-Silicone Pressure Sensitive Adhesive Tape
CHR 2975-8R is manufactured from silicone rubber/fibreglass
cloth backing coated with high-temperature adhesive.
Features/Benefits :
2975 tape is designed to withstand both the punishing abrasion
of grit blasting and the extreme temperatures/pressures
associated with the plasma spray process. The adhesive is a
high-temperature silicone, which allows the product to withstand
continuous temperatures up to 260°C and also prevents tape
slippage after application. These tapes have excellent strength
and flexibility, which allows for easy wrapping of complex shapes
and minimizes wrinkling during the flexing of cables.
Applications :
2975 is used in the plasma spray process: a method of applying
thin coatings of metal or high-temperature ceramics to a
surface. The coating is sprayed at high pressure and at extreme
temperatures. The tape is applied adjacent to areas of parts,
which are to be plasma sprayed. These tapes protect these
areas both from the grit blasting, which is used as a surface
preparation, and from the actual plasma spray coating. The
aerospace industry is the prime market for the use of plasma
spray tapes, specifically, jet engine manufacturers, overhaul
centres, major airline maintenance centres, Air Force Bases, and
Naval Air Rework Facilities (NARF’S).
