^{3M 聚酯膠帶 8403}

 www.phi.com.tw : 3M Polyester Tape 8403 has a silicone adhesive for composite bonding and splicing of many silicone coated papers and films.

• 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.

• 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.
