OPTICAL RETARDED CURING TYPE ADHESIVE FOR OIL SURFACE

摘要

PROBLEM TO BE SOLVED: To provide an optical retarded curing type adhesive for an oil surface solving problems that (1) high-rigidity adherends (e.g. steel plates) are easily peeled when mutually bonded because oil adhesiveness is bad and (2) a thin film of only several hundreds ofμm at most can be cured even when a sensitizer is used because a photo-cationic polymerization initiator generally has an activity thereof in ultraviolet light at a short wavelength. SOLUTION: The optical retarded curing type adhesive for the oil surface is characterized as further comprising an oxetane resin and a thermoplastic elastomer in an optical retarded curing type adhesive comprising at least an epoxy resin, the photo-cationic polymerization initiator and a retarder.
