歐洲專利號：WO2014129192

摘要：Provided is an adhesive which is capable of forming a packaging material for batteries, said packaging material having excellent moldability and maintaining high bonding strength even after a long-term endurance test. A polyurethane adhesive for packaging materials for batteries according to the present invention contains a base material and a curing agent. The base material contains an acrylic polyol (A) having a number average molecular weight of 10,000-100,000 and a hydroxyl number of 1-100 mgKOH/g. The equivalent ratio of the isocyanate groups derived from an aromatic isocyanate (B) contained in the curing agent relative to the hydroxyl groups derived from the acrylic polyol (A), namely NCO/OH is set to 10-30.
