^{3M 聚酯膠帶 8902}

3M Polyester Tape 8902 is a high temperature tape with a silicone adhesive for use as a masking in powder coat painting and is designed to provide clean removal during masking operations involving high temperatures and pressure.

• Polyester film that retains flexibility and thermal resistance and is abrasion, chemical and thermal resistant to help reduce failures due to cracking and backing deterioration.
• Silicone adhesive for higher heat resistance than many other adhesives to help reduce failure due to softening, oozing and adhesive transfer.

• Composite and metal bonding as it removes cleanly from stainless steel, anodized aluminum and glass after a 5 hour bake cycle at 350°F (177°C).
• Masking edges of overlap seams in metal bonding process where excess epoxy (“flash”) flows onto tape as clean-up is complete upon tape removal.
• Holding parts or vacuum bags during bonding process.
• Masking parts for powder coat painting.
• Splicing silicone treated materials.
• Composite bagging operations or to remove flashing after bonding.
