ADHESIVE COMPOSITION CAPABLE OF MAINTAINING ADHESION AT ROOM TEMPERATURE AND HIGH TEMPERATURES AND HAVING LOW GEL FRACTION CHANGE AND VISCOSITY CHANGE ACCORDING TO TEMPERATURE CHANGE AND SHORT CURING TIME

摘要

PURPOSE: An adhesive composition is provided to improve crosslinking rate without damage of storage stability, to reduce curing time, and to have excellent adhesive durability even at high temperatures, thereby being used as not only a gluing agent but also a sticking agent.;CONSTITUTION: An adhesive composition contains an acrylic copolymer having an isocyanate and a crosslinkable functional group and an isocyanate-based crosslinking agent, and an acid anhydride. The cyclic acid anhydride is one or more selected from a maleic anhydride, a phthalic anhydride, an acetic anhydride, a nadic anhydride, and a derivative thereof. The adhesive composition additionally includes a silane coupling agent, a crosslinking accelerator, or a mixture thereof. The acrylic copolymer contain 100.0 parts by weight of a C1-12 alkyl group-containing (meth)acrylate monomer and 0.1-30 parts by weight of a crosslinkable functional group-containing polymerizable monomer.;COPYRIGHT KIPO 2013
