POLYURETHANE LAMINATE, METHOD FOR PRODUCTION OF THE SAME, AND SEALING MATERIAL AND DAMPING/BUFFERING MATERIAL EACH UTILIZING THE SAME

摘要

[PROBLEMS] To provide: a polyurethane laminate which is free of the concerns about bleeding, has good follow-up properties and hermeticity due to its low hardness, and has reduced surface adhesion and good reusability and workability; and a sealing material and a damping/buffering material each utilizing the polyurethane laminate. [MEANS FOR SOLVING PROBLEMS] Disclosed are: a polyurethane laminate which comprises a polyurethane resin and a protective layer formed by applying a mixture of silyl isocyanate and a silicone polyol on the surface of the polyurethane resin at a ratio of 0.1 to 5 g/m2 and curing the applied mixture, which has an Asker C hardness of 30 or less at room temperature, and which has a 180-degree peel adhesion force against a PET film of 0.1 N/10 mm or less; and a sealing material and a damping/buffering material each utilizing the polyurethane laminate.
