Metal Spray Masking Tape

Grit Blast Tapes

Grit Blasting is a surface preparation process in which a high-pressure stream of abrasive material is directed at the surface of a part of component to create shape, add surface texture (rough or smooth), or to remove surface coatings or contaiminants. The grit blast process is used in thermal spray facilities. The type of grit media used depends on the application and the type of substrate. To effectively prepare the component for the thermal spray coating, sharp, angular media, such as aluminium oxide, is blasted at high pressure towards a target surface to remove unwanted coatings and to apply a desired (roughened) surface texture. Green Belting Industries masking materials, such as 170-10S Green are well suited to endure both the grit blast and spray coating processes, thus saving significant time and cost.

Most thermal spray facilities use abrasive blasting to etch and prepare surfaces to snure good bonding surfaces prior to the coating application. A lot of the time, only selected areas of a product require surface preparation, so non-target areas must be protected from the abrasive grit spray. The same non-target areas are also masked to protect them from overspray during the coating process.

Depending on the size of grit and coating method being used, recommended materials include: HVMT Orange, 170-10S YL & 20S YL, 170-10S Green, 170-10S Red, 179-20S or 25S.
