Abstract:
A radiation curable precursor coating composition for the preparation of a non-blocking, heat activatable adhesive, said precursor composition comprising:a radiation curable acrylic material selected from the group consisting of isobornyl methacrylate, isobornyl acrylate, 1,6-hexanediol diacrylate, and combinations thereof;a radiation curable elastomeric material; anda hydrocarbon tackifier material having a softening temperature ranging from approximately 50.degree. C. to approximately 200.degree. C., wherein when said acrylic material and said elastomeric material are cured, said coating composition is non-blocking at room temperature, but when said cured composition is heated to a temperature above both the softening temperature of said hydrocarbon tackifier and the Tg of the cured coating composition, said composition becomes adhesive.
