COATING COMPOSITIONS AND COATINGS FORMED THEREFROM

摘要

Novel coating compositions including a polymer, a silane and a hydrazide. The polymer having at least one reactive functional group. Optionally, the coating composition includes a pigment. Coatings made from such compositions are also described. Methods of preparing a coating by applying the coating composition to a substrate and curing to form a film are also described herein. The preferred coating compositions are formaldehyde-free and isocyanate-free, can be air cured and provide coatings that exhibit improved adhesion to the substrate, improved print and block resistance and improved solvent and water resistance.
