<P>PROBLEM TO BE SOLVED: To provide an isocyanate-terminated prepolymer composition, a hydroxy-containing curing agent composition and a catalyst composition which are used for formation of a thermosetting polyurethane elastomer, a thermosetting polyurethane elastomer forming composition capable of shortening the molding cycle of a thermosetting polyurethane elastomer-molded product to be used as a component of industrial equipment which includes the compositions, and to provide a method for producing the thermosetting polyurethane elastomer-molded product, capable of minimizing hardness creep and contamination of other components by blooming, bleeding or the like. <P>SOLUTION: The thermosetting polyurethane elastomer-forming composition includes an isocyanate-containing urethane prepolymer (A); a hydroxy-containing curing agent (B); and a catalyst (C). The hydroxy-containing curing agent (B) includes a triol (B1) having a number average molecular weight of 270-1,200 and a diol (B2) having a number average molecular weight of 470-3,000. As the catalyst (C), at least titanium triethanol aminate (C1) is used, and the content of the catalyst (C1) to the whole composition is 50-200 ppm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
