Beschreibung
Zusammenfassung:	This disclosure provides a pigmented primer composition for forming an n-acyl urea coating on a substrate. The pigmented primer composition includes a polycarbodiimide-polyurethane hybrid. The pigmented primer composition also includes an acid functional polymer and an organic solvent, and includes less than or equal to 10 weight percent of water based on a total weight of the pigmented primer composition. The pigmented primer composition also includes a pigment, an inorganic filler, and less than about 100 parts by weight of toluene diisocyanate per one million parts by weight of the pigmented primer composition. The n-acyl urea coating exhibits corrosion resistance of 2 to 10 as determined using ASTM B117 and ASTM D-1654-08 on a substrate that is unpolished cold rolled steel, aluminum, or galvanized steel.
