Carbamate functional oligomers and coatings therefrom

摘要

This invention involves a carbamate functional polymer or oligomer made by reacting a cyclic carbonate with ammonia or a primary amine, then reacting the resulting hydroxycarbamate with a polyfunctional material containing groups reactive with hydroxyl groups to form a polyfunctional carbamate. The polymer formed is mixed with an aminoplast, coated on a substrate and cured to form a crosslinked coating.
