Abstract
A moisture-curable hot-melt adhesive having an excellent balance of environmental friendliness, compatibility of ingredients, early-stage adhesive strength, heat resistance after moisture curing, tack free time, etc. and a method of manufacture for this hot-melt adhesive. A moisture-curable hot-melt adhesive which contains a urethane polymer that has a terminal isocyanate group and a moisture-curable hot-melt adhesive that contains urethane modified resin, has a residual percentage of isocyanate compound of 5 wt. % or less, and has a heat-resistant softening temperature after moisture curing of 60° C. or higher, has an excellent balance of the aforementioned. Urethane modified resin can be obtained by reacting a resin derivative that has a hydroxyl group with an isocyanate compound, and a moisture-curable hot-melt adhesive can be produced by mixing urethane-modified resin, polymer, and isocyanate compound. The adhesive is particularly useful for building materials, electronics materials, the automotive field, and the like.
