ABSTRACT:
The present invention relates to the preparation and use of novel polyurethane polyuretidione crosslinking agents in solvent and water borne coatings systems. These polyuretidione polyurethanes are characterized by their relatively low solution viscosity, and the ability to provide a relatively high crosslink density in the final, cured film, and thereby, coatings with the excellent physical properties and resistance to chemical and environmental exposure of known polyurethane systems without the potential for worker exposure to toxic isocyanates. This invention also relates to a process for the production of these polyuretidiones and their use in pseudo-one and two component coating compositions.
