TST406X6 - TechSouth TST40 Thermal Spray Masking Tape, 6-Inch Width

Tough Masking for Blasting and Spraying

When you are prepping parts for metallizing or running a grit blast cabinet, you need a tape that can take a beating. The TechSouth TST40 6 X 6 Standard System is built exactly for that. This isn't your average masking tape; it's a heavy-duty industrial shield made from fiberglass cloth and coated with tough silicone rubber. Whether you are flame spraying a shaft or sandblasting a bracket, this tape stands between your part and the abrasive media, ensuring only the areas you want treated get hit.

Heat is the enemy of most tapes, causing them to melt, burn, or leave a nasty sticky mess that takes hours to clean off. The TST40 is different. It handles heat up to 500°F without flinching. You can run your thermal spray process knowing the tape won't curl up or carbonize on the part. When the job is done and the part has cooled, the tape peels off in one piece, leaving the metal underneath clean and ready for the next step. No scraping, no solvent scrubbing, just a clean line.

The 6-inch width is perfect for covering large areas quickly. Instead of running multiple strips of narrow tape and risking gaps, you can lay down a wide swath of protection in seconds. The silicone adhesive sticks hard to metal, even on curved surfaces, but releases easily when you pull it. It's flexible enough to wrap around corners and edges, giving you a tight seal that keeps grit and overspray out. If you are tired of cheap tapes failing in the blast booth or melting under the torch, the TST40 is the upgrade your shop needs.

This tape is a standard in job shops that handle pump repair, shaft buildup, and surface coating. It replaces expensive metal fixtures and saves you time on every job. Keep a roll of TST40 in your cabinet for those critical masking jobs where failure isn't an option.
