Features
• Designed to provide clean removal during masking operations involving high
temperatures and pressure.
• Blue color makes it easy to see for removal.
• Polyester film that retains flexibility and thermal resistance to help reduce
failures due to cracking.
• Abrasion, chemical and thermal resistance that helps reduce failures due to
backing deterioration.
• Silicone adhesive which has a higher heat resistance than many other adhesives
to help reduce failure due to softening, oozing and adhesive transfer.
