Abstract
This disclosure provides a solvent-borne system for forming an n-acyl urea coating on a substrate. In one embodiment, the solvent-borne system comprises a polycarbodiimide-polyurethane hybrid. The solvent-borne system also comprises an acid functional polymer and an organic solvent, and comprises less than or equal to 10 weight percent of water based on a total weight of said solvent-borne system. The solvent-borne system also comprises less than about 100 parts by weight of toluene diisocyanate per one million parts by weight of the solvent-borne system.
