Abstract
Isocyanate prepolymer compositions can be cured quickly and thoroughly in the presence of atmospheric moisture by reacting them with a curing system that includes a mixture of (1) an oxazolidine moisture scavenger and curing agent and (2) a hydroxyl curing agent. The oxazolidine moisture scavenger/curing agent can be monocyclic oxazolidine or bicyclic oxazolidine. The hydroxyl curing agent preferably is a polyhydric compound. If desired, an organic solvent, a catalyst, and/or fillers can be used with the invention in order to speed the curing reaction or improve the physical and mechanical properties of the final polymer product.
The present invention enables high quality polyurethane/polyurea polymers to be formed in thick layers under various environmental conditions, including humidity, that render the invention suitable for use in the field.
