EXTREME HIGH TEMPERATURE TAPE AND BACKINGS THEREOF

摘要

Described herein is a paper-based backing and a tape that may be used in extreme high temperature applications. In one embodiment, the tape comprises (a) a backing comprising a paper and a saturant, wherein the saturant comprises a C2 to C6 (meth)acrylic ester; and (b) an adhesive disposed on the backing, wherein the adhesive comprises a crosslinkable (meth)acrylate polymer and a heat-activatable crosslinking agent, wherein the heat-activatable crosslinking agent is activated at a temperature of at least 80°C. In another embodiment, the backing comprises: (a) a paper and (b) a saturant, wherein the saturant comprises a butyl (meth)acrylic ester wherein the butyl (meth)acrylic ester permeates the paper and wherein the saturant is essentially free of a crosslinker, and the backing has an autoignition temperature of greater than 425°F (218°C).
