  • Publication number: 20100130629
    Abstract: Disclosed is a catalyst composition for polyurethane resin production which contains (A) triethylenediamine, (B) a specific polyisocyanurating catalyst and/or (C) a specific highly temperature-sensitive catalyst. By using this catalyst composition, a polyurethane resin can be molded with good curability, while suppressing initial reactivity. Consequently, a polyurethane resin having excellent moldability and fluidity can be produced with high productivity by using the catalyst composition. The thus-obtained polyurethane resin is suitably applicable to shoe soles. The component (B) is selected from the group consisting of alkali metal salts of carboxylic acids, quaternary ammonium compounds expressed as R1R2R3R4N+,X?, N,N,N?-trimethylaminoethylethanolamine, and 2,4,6-tris(dimethylaminomethyl)phenol, while the component (C) is selected from the group consisting of triazole salts and benzotriazole salts of 1,8-diazabicyclo[5.4.0]undecene-7 or 1,5-diazabicyclo[4.3.0]nonene-5.
