PURPOSE:To provide a curable resin composition composed of a specified carbodiimide-modified liquid diphenylmethane diisocyanate, a polyether polyol having a specified molecular weight and others, excellent in shelf life and compatibility and useful for a belt, a sealing material, etc. CONSTITUTION:This curable resin composition is composed of (A) a carbodiimide-modified liquid diphenylmethane diisocyanate having 9.0 to 17.0wt.% ratio of modification with carbodiimide, (B) a polyether polyol having 600 to 4000 molecular weight, e.g. polypropylene ether glycol and further (C) a low-molecular active hydrogen group-containing compound having 62 to 600 molecular weight, e.g. ethylene glycol and containing an additive as necessary. In addition, a curable resin can be obtained by pouring this composition into a mold of 30 to 90 deg.C and curing it for 5 to 12hr. |
