Emulsifier-free, heat-curable coating material, its preparation and use

摘要

A coating material is described which exhibits high resistance to chemicals and is emulsifier-free. The coating material is useful as a lacquer layer coating on metallic substates such as automobiles. The coating material is based upon a polyester oligomer/polyacrylate wherein the polyacrylate contains hydrophilic and hydrophobic portions and the polyester contains hydroxyl functions. Capped polyisocyanates are also included in the coating material.
