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.
