More Information
Summary:Provided is a polyurethane resin composition comprising: a polyurethane resin obtained by reacting an organic diamine and an alkanol amine with a urethane prepolymer that is made by reacting a polyisocyanate, including tolylene diisocyanate, with a high-molecular polyol and that has an isocyanate group at a terminal thereof, wherein [NCO (total)]/[OH], [NCO (TDI)]/[OH], the hydroxyl value of the polyurethane resin, and the ratio between the organic diamine and the alkanol amine are controlled; and a mixed solvent including an ester-based solvent and an alcohol.
