Saint-Gobain CHR® H7525 Glass-Silicone Backing Silicone Adhesive Pressure Sensitive Tape
Categories: Polymer; Adhesive; Tape; Thermoset; Silicone

Material Notes: CHR® H7525 and H7575 (HVOF) are heavy-duty pressure-sensitive tapes used for thermal spray masking. They are manufactured by combining multiple layers of silicone rubber, aluminium foil and fibreglass coated with aggressive high-temperature silicone adhesive. HVOF means High Velocity Oxygen Fuel spray technique.

Features/Benefits: CHR® H7525 and H7575 have exceptional abrasion resistance and adhesion properties, which allows the tapes to wear very well during the spraying process. These tapes are also very conformable and can be used for many part configurations. They can continuously withstand temperatures up to 260 °C.

Applications: CHR® H7525 and H7575 are used as high-temperature masking tapes in thermal spray and high velocity oxygenated fuel (HVOF) processes. The tapes are used to protect portions of the part being processed so that they are not exposed to spray. They are used primarily in the aircraft industry in their repair shops as well as in other markets where thermal spraying is used.
