<P>PROBLEM TO BE SOLVED: To solve the following problem: although conventionally the preservability is stabilized and a composition having excellent curability is obtained by treating the surface of a curing agent, the production process for treating the surface of a polyamine powder is complicated and problems are present in the stabilization of quality and the increase of processing fees; and further there is no cured product of a prepolymer having a polyester skeleton or a polyether skeleton which are possessed by many of the conventionally used prepolymers, and simultaneously satisfying flexibility, heat resistance and moisture resistance. <P>SOLUTION: A curable resin composition comprises the following components (A) and (B). Component (A) is a prepolymer having an isocyanate group at a terminal obtained by reacting the following components (a-1) with (a-2). Component (B) is a powder of a compound having two or more primary amine groups and/or secondary amine groups in one molecule. Component (a-1) is a hydrogenated castor oil-based polyol; and component (a-2) is a compound having two or more isocyanate groups in one molecule. <P>COPYRIGHT: (C)2010,JPO&INPIT |
