Application Ideas • Masking edges overlap seams in metal bonding process where the excess epoxy
(“flash”) flows onto the tape. Clean-up is complete when the tape is removed.
• Protective overall mask on panels to mild caustic or acid bath etching. Helps
prevent scratches during handling and provides desired masking during metal
bonding and fabrication.
• Holding of parts or vacuum bags during bonding process.
• Mask for metal in acid or caustic chemical milling baths.
• Masking parts in anodizing processes.
• Splicing of silicone coated papers and films.
• Paint masking of materials subjected to high temperatures
3M™ Polyester Tape 8403, 2.3 mil (0.06 mm) polyester film tape with green pigmented silicone adhesive.
3M™ Polyester Tape 8403, masking for high temperature appllications, adheres well to silicone coated surfaces. The green color and silicone adhesive make for easier identification and application when splicing silicone treated paper.
