Abstract

PURPOSE: To produce a urethane composition which does not foam even in the presence of water, by mixing and reacting a curing agent, a specified metal compound, and a prepolymer obtained from an isocyanate and castor oil, linseed oil or its copolymerization derivative.
CONSTITUTION: A liquid or paste prepolymer is obtained by reacting an isocyanate containing at least two terminal isocyanato groups with at least one member selected from castor oil, linseed oil or an active hydrogen-containing copolymerization derivative thereof. To the prepolymer obtained are added a curing agent and at least one member selected from the group consisting of a hydroxide, oxide, basic salt, complex salt and double salt of a metal selected from Groups II, III and IV of the periodic table. The resulting mixture is reacted and cured. In the preparation of the prepolymer, there can be added and reacted a substance which reacts with castor oil or linseed oil to form an active hydrogen-containing castor oil or linseed oil copolymerization derivative, such as a polyester or a polyether, in addition to at least one member selected from the group consisting of castor oil, linseed oil or an active hydrogen-containing copolymerization derivative thereof.
