Thermal Spray Tapes

High temperature thermal tapes for plasma spray, flame spray, and grit blasting applications

Plasma spray and flame spray thermal tapes are all created to withstand high temperature and the most demanding plasma spray, flame spray, and grit blasting applications. These thermal spray tapes are known to resist fray and will release easily without leaving adhesive residue.

CHR® 2905-7R– has a wide variety of uses in the plasma thermal spray market and comes with a release liner. It is most widely used as a high temperature masking tape for plating or plasma spray coatings. 2905-7R is also used as a holding tape, as a wrap for coils and transformers, and for high temperature splicing. It is extremely stable allowing it to withstand temperatures up to 500°F. Other characteristics include excellent abrasion and edge tear resistance and exceptional flex strength.

CHR® 2915-7– performs as a light duty plasma or flame spray masking tape. It is a very versatile tape without a release liner. Applications range from general industry electrical maintenance to high-temperature slicing and wrapping. Some specific applications are over-wrap on motor rewinds, protective wrapping for wire and cables, and high temperature masking tape for welding stainless steel. 2915-7 is strong, abrasion, solvent, and temperature resistant, and thermally stable. It can be used in applications that require continuous temperatures of up to 500°F.

CHR® 2975-8R/CHR® 2975-8RK– 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 extreme temperatures. The tape is applied adjacent to areas of parts, which are to be plasma sprayed. This tape protects these areas from both 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 centers, major airline maintenance centers, Air Force Bases, and Naval Air Rework Facilities (NARF’S). This 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 500°. This tape has excellent strength and flexibility, which allows for easy wrapping of complex shapes and minimizes wrinkling during the flexing of cables. 2975-8R has a yellow PVC release liner and 2975-8RK has a fluorosilicone release liner.

CHR® HV60-18R/CHR® HV60-26R– is pressure sensitive adhesive tape specifically designed to withstand the extreme operating conditions found in high velocity oxygen fueled (HVOF) thermal spray applications. Product performance has been validated in both liquid and gas fueled systems with a wide range of coating materials including metal, metal alloys, and carbides. This tape features high temperature resistance, exceptionally high abrasion resistance, functions as a thermal insulator, and is highly flexible and conformable. It leaves no adhesive residue when removed.

Tech Tip– Thermal spray tapes are an excellent choice for combining conformability with thermal and abrasion resistance while protecting adjacent surfaces from spray.
