HIGH SPEED CURING HALOGEN FREE ADHESIVE COMPOSITION, COVERLAY FILM AND ADHESIVE FILM USING THE SAME

摘要

PURPOSE: A halogen-free quick-hardening adhesive composition is provided to avoid the generation of gases harmful to the human body since a halogen is not included and to ensure excellent fire retardancy, low hardening temperature, and short hardening time. CONSTITUTION: A halogen-free quick-hardening adhesive composition comprises 100 parts by weight of a halogen-free epoxy resin, 30-90 parts by weight of a thermoplastic resin, 5-60 parts by weight of a hardener for epoxy, 1-50 parts by weight of benzoxazine, and 5-100 parts by weight of a phosphorous-based flame retardant represented by chemical formula 1. A cover lay film includes a pressure-sensitive adhesive layer formed by applying the halogen-free adhesive composition to an electric insulating film and a release substrate laminated on the adhesive layer.
