PRESSURE-SENSITIVE ADHESIVE RESIN COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE PLATE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive resin composition and a pressure-sensitive adhesive plate excellent in adhesion, sealing property and reworking property, and exhibiting an easy handling property in the use as a sheet metal material. SOLUTION: The pressure-sensitive adhesive resin composition comprises a thermoplastic styrene-based elastomer, a hydrogenated terpene as a tackifier and a paraffin-based oil as a softener. The styrene based elastomer is a block copolymer which has a polymer composed of a hydrocarbon chain and polystyrenes bonded on both ends thereof. The resin composition comprises 100 pts.wt of the styrene based elastomer, 100-250 pts.wt of the hydrogenated terpene and 40-150 pts.wt of the paraffin based oil. COPYRIGHT: (C)2008,JPO&INPIT
