Abstract

PURPOSE: To promote resin curing uniformly and obtain a urethane resin having excellent weather resistance, by treating an isocyanato-terminated urethane resin with a vapor-phase tertiary amine.
CONSTITUTION: An isocyanate compound having, in the molecule, at least two isocyanato groups attached to an aromatic nucleus through methylene groups, e.g., 1,2-bis(isocyanatomethylbenzene), is reacted with an active hydrogen compound, MW 300W10,000, functionality 2W4, at 10W120°C for 1W10 hr, to obtain an isocyanato-terminated urethane resin. Then, this urethane resin is cured by treating it with a gas containing 10W1,000 ppm vapor-phase tertiary amine (e.g., trimethylamine) at 0W100°C for 1W10 min.
