Application Ideas • Splicing of silicone treated webs. • Masking parts for powder coat painting • Holding parts or sealing vacuum bags during processing • Masking edges of overlap seams in metal bonding process where excess adhesive flows onto tape. Minimizes clean-up on tape removal. 3M™ Polyester Tapes 8901 • 8902 • 8905 Application Ideas (continued) • Composite bonding – sticks well to molds treated with release agent, works as a flash breaker tape on removal of part from mold, seals vacuum bags if vacuum bag treatment is part of the process. • Provides a good barrier for separation of dissimilar metals. • Holding silicone or silicone treated parts. Storage Store under normal conditions of 60º to 80ºF (16º to 27ºC) and 40 to 60% R.H. in the original carton.
