DeWAL Industries has introduced a line of high temperature, silicone-free adhesive tapes for the aerospace composite industry. The tapes are designed for low out-gassing applications requiring EMS 595. The line includes a woven glass tape, a foil/glass laminate tape, a red polyester tape and high density PTFE.
"It is becoming an ever increasing problem in sensitive manufacturing processes to introduce silicone elements," said a company spokesperson. "DeWAL has addressed this issue by formulating some of its tapes in versions which contain no silicone. While ideal for the aerospace composite industry, they are additionally used in automotive and electronic applications where silicone can also be of concern."
DeWAL's polyester tapes for composite lay-up are DW 915-1 and DW915-2. They are 100% silicone free, offering a high temperature, high bond, clean release acrylic adhesive. Both pass the ASTM E595 Low Outgassing Test for no outgassing contamination. They use a 1 mil film and 2 mil film respectively, both are engineered to be conformable.
DeWAL's PTFE tape for use as composite tool coat is DW716-2HD. The printable glass tape, DW379, is used in aerospace blanket seaming and also as a wire harness and transfromer wrap.
The fourth tape in this new series, DW417, is a flexible dead soft foil supplied on a release liner. "The aluminum laminate makes it an ideal heat shield tape," said the spokesperson.
As with the polyester tapes, the other three tapes also pass the EMS 595 requirement and offer low out-gassing, silicone free operation.
