THERMOSETTING COMPOSITION

摘要

An object of the invention is to provide a heat curable composition having both of an excellent storage stability and low-temperature curability. The heat curable composition of this invention comprises (A) a polyisocyanate compound and an urethane prepolymer having a terminal active isocyanate group which is prepared by reacting a polyol component with an excess amount of a polyisocyanate compound, which are used each alone or in a combination threof; and (B) a fine particles-coated amine which is prepared by coating an active amino group on the surface of a solid amine having a melting point of≥50 DEG C and a mean particle size of≤20 mu m with fine particles having a mean particle size of≤2 mu m in a ratio of the solid amine / the fine particles of 1/0.001 to 0.5 by weight.
