MOISTURE-CURING TYPE HOT MELT ADHESIVE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a moisture-curing type hot melt adhesive composition exhibiting an allowable amount of generated mist of a free monomeric isocyanate on melting it in a range not becoming an issue for safety and hygiene, showing an extremely low yellowing property on being exposed with ultraviolet light and also having an excellent curing reactivity. SOLUTION: This moisture-curing type hot melt adhesive composition is a composition containing a urethane prepolymer obtained by the reaction of a diisocyanate compound with a polyol compound and having isocyanae group in its terminal. The diisocyanate compound is norboranane diisocyanate.
