DeWAL Industries (Narragansett, RI, US) has introduced a new line of high-temperature, silicone-free adhesive tapes for the aerospace composites market. The tapes are said to be ideal for low out-gassing applications. The product line includes a woven glass tape, a foil/glass laminate tape, a red polyester tape and a high-density PTFE tape. DeWAL’s new polyester tapes for composite layup processes are DW 915-1 and DW915-2. They provide a high-bond, clean-release acrylic adhesive, pass the ASTM E595 Low Outgassing Test, and use a 1-mil and 2-mil film respectively. DeWAL’s PTFE tape for use as a 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 reportedly makes it an ideal heat shield tape.
