Tacky blend of butadiene-acrylonitrile copolymer thermosettable material having acrylate and epoxy groups peroxide and epoxy curing agent

摘要

Sheet material coated with heat-hardenable, tacky adhesive to form adhesive tapes, bonding films and similar products. The tacky adhesive layer provides for temporarily adhering one structure to another at ordinary temperatures and can be subsequently heat-hardened to a strong, permanent bond. Another aspect of the invention relates to the tacky, heat-hardenable adhesive compositions themselves.
