Title:
MOISTURE-CURING URETHANE COMPOSITION
Document Type and Number:
Japanese Patent JP3868124
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a moisture-curing urethane composition which can be subjected to accelerated curing even under high-temperature high-humidity conditions without foaming and can develop excellent tensile stress (modulus), tensile strength, and elongation when cured.
SOLUTION: This composition comprises 100 pts.wt. (A) urethane prepolymer prepared by reacting a polyether triol having an average molecular weight of 1,000-7,000 or a mixed polyol comprising a polyether triol and a polyether diol and having an average molecular weight of 1,000-7,000 with a diisocyanate in an NCO/OH equivalent ratio in the range of 1.1-2.5 and 5-20 pts.wt. (B) urethane compound prepared by reacting a polyester diol and/or a polyether diol each having an average molecular weight of 500-3,000 with norbornane diisocyanate in an NCO/OH equivalent ratio in the range of 1.5-2.1.
