PRODUCTION OF LARGE AREA LAMINATE

摘要

PROBLEM TO BE SOLVED: To produce a large area laminate excellent in initial adhesion, normal state adhesion, bonding strength and productivity by using a large area base material low in heat conductivity and a large area synthetic resin foam as a surface material. SOLUTION: A large area laminate is produced by applying a humidity curable urethane type reactive hot melt adhesive having a long tack free time at the normal temp. to one of or both of a large area base material low in heat conductivity being a surface material and a large area synthetic resin foam being a core material and bonding the base material and the synthetic resin foam under pressure.
