Abstract

PURPOSE: To water-curable urethane composition which has excellent storage stability and forms a hydrated gel when reacted with water at room temperature, prepared by mixing a hydrophilic polyisocyanate with an isocyanato-masking agent having an OH group in the molecule.
CONSTITUTION: A hydrophilic polyisocyanate having at least two NCO groups in the molecule is mixed with an isocyanato-masking agent having an OH group in the molecule, selected from hydroxypyridine, hydroxyquinoline and a phenol having a pKa of 5W9.5 so that the ratio of the NCO groups of the polyisocyanate to the OH groups of the masking agent, OH/NCO, is 0.05W2. As the hydrophilic polyisocyanate which can be used there is mentioned a urethane prepolymer having at least two free NCO groups in the molecule, prepared by reacting a polyisocyanate compound with a hydrophilic polyol such as an ethylene oxide addition polymer, MW 1,000W2,000.
