Abstract
Solid vinyl ether terminated curing agents for powder coatings can be prepared by reacting an aliphatic diisocyanate with a polyol and then with a hydroxy vinyl ether, or by reacting an aliphatic polyisocyanate with a hydroxy vinyl ether. Powder coatings based on the so prepared curing agents are extremely useful for coating heat sensitive substrates by exposure to ultraviolet light, heat, or both.
