Heat-sensitive adhesive material, method of preparing same and method of using same

摘要

A heat-sensitive adhesive material including a substrate and a heat-sensitive adhesive layer provided thereon. The adhesive layer has one of the following properties (a) and (b): (a) the heat-sensitive adhesive layer, when thermally activated, exhibits an adhesive strength in the range of 1800-3500 gf/40 mm at 0-10° C.; (b) the heat-sensitive adhesive layer, when thermally activated, exhibits a scratch resistance in the range of 150-500 gf at 0° C.
