摘要
PROBLEM TO BE SOLVED: To provide a heat-cured urethane elastomer molding for the parts of industrial equipment which has excellent properties of tensile strength especially at a condition of 50-70°C.;SOLUTION: The heat-cured urethane elastomer molding is obtained by injecting to cure a liquid mixture of (A) an NCO-terminal urethane prepolymer and (B) an OH-terminal curing agent into a mold and then removing from the mold, and (B) the OH-terminal curing agent contains (B1) a compound represented by formula (1) as one of the components. In the formula (1), [R1, R2 and R3 may be mutually all the same or different, and one or two of them may be hydrogen(s), but at least one is an alkyl group having a carbon number of 1 or more].;COPYRIGHT: (C)2002,JPO
