URETHANE RESIN COMPOSITION, ADHESIVE AND COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a room temperature setting urethane resin composition usable in rainy weather or a hot and humid condition and suitable as an adhesive and a coating material. SOLUTION: This urethane resin composition contains (a) a polyisocyanate compound, (b) a polyol compound, (c) a hydroxide and (d) glycerol. The composition is a two-pack type urethane resin composition composed of the 1st agent containing the component (a) and the 2nd agent containing the components (b), (c) and (d). The component (a) is preferably a prepolymer having unreacted isocyanate group and produced by reacting a polyol compound with a polyisocyanate compound and the hydroxide (c) is preferably calcium hydroxide.
