Protecting mission-critical parts from overspray and splash can be a challenge when thermal spraying is needed. DeWAL thermal spray solutions protect parts even in the most unrelenting bombardments, no matter what the angle of spray, the base metal, the temperature or the substrate. DeWAL Thermal, Plasma and HVOF tapes are free of carbonizing materials and form a protective mask for metal or ceramic plasma spraying, arc spraying, HVOF and grit blasting. Engineered to aggressively adhere, DeWAL thermal spray masking tapes ensure sharp edges but remove quickly and cleanly. These products are available in single- and double-ply options. Our double-ply tapes perform in the most severe applications, providing an economical solution to multi-layer masking.

Additionally, DeWAL® DW 500 Pressure Sensitive Tape is a high-temperature masking tape for use during plasma flame spraying. It provides superior high temperature protection during both grit blasting and plasma metallization operations. This one-step plasma masking tape is engineered silicone rubber with glass cloth backing coated with an aggressive, high-temperature silicone adhesive. It will withstand the challenges of grit blast and plasma spray while protecting parts from overspray and splash.
