ONE-PACK MOISTURE-CURING TYPE URETHANE-BASED HOT MELT ADHESIVE COMPOSITION AND METHOD FOR USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a one-pack moisture-curing type urethane-based hot melt adhesive composition having excellent initial quick curability and sufficient adhesive strength after moisture curing and to provide a method for using the same.;SOLUTION: The one-pack moisture-curing type urethane-based hot melt adhesive composition comprises a urethane prepolymer having at least one isocyanate group and at least one (meth)acryloyl group in the molecule and has photo-curability. The method for using the one-pack moisture-curing type urethane-based hot melt adhesive comprises a step of coating each adherend surface of mutually bonded adherends with the one-pack moisture-curing type urethane-based hot melt adhesive composition, forming coated films, then irradiating each coated film with light so as to provide 100-3,000 mJ/cm² cumulative quantity of light, providing pre-cured films, subsequently mutually bringing the pre-cured films into contact and bonding the films.;COPYRIGHT: (C)2009,JPO&INPIT
