Title:
MOISTURE-CURABLE HOT-MELT URETHANE RESIN COMPOSITION, LAMINATE, AND SHOES
Document Type and Number:
WIPO Patent Application WO/2018/116681
Kind Code:
A1
Abstract:
The present invention provides a moisture-curable hot-melt urethane resin composition which contains an isocyanate-group-containing urethane prepolymer that is a product of the reaction of one or more polyols (A) with polyisocyanates (B), characterized in that the polyisocyanates (B) were (B-1) an aliphatic polyisocyanate and/or an alicyclic polyisocyanate and (B-2) an aromatic polyisocyanate in a (B-1)/(B-2) ratio by mass of from 10/90 to 95/5. It is preferable that the polyols (A) comprise (A-1) a crystalline polyol and (A-2) a noncrystalline polyol. Even when applied to bases made of rubber, the moisture-curable hot-melt urethane resin composition of the present invention can attain excellent initial creep characteristics and excellent initial strength.
