DW 497 is a white silicone rubber-coated glass fabric with a high temperature silicone adhesive.
The silicone rubber is tough and abrasion resistant to withstand high temperatures and grit blasting impact.
The silicone adhesive provides excellent adhesion at high temperatures yet will remove cleanly.
This tape is used as a masking tape in plasma flame spraying.
DW 497 is a one step masking tape used both in the “grit blast” and “plasma spray” process all in one masking application. It is very good in preventing bridging during the metallization process
