ANHYDROUS COMPOSITION AS COATING MATERIAL FOR FUNCTIONAL LAYER OF MULTICOAT PAINT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a composition which forms functional layers functioning as a coating material in multicoat paint systems having at least three paint systems without intermediate drying (3C1B (3-coat 1-bake) multicoat paint systems) and which does not have disadvantages of the prior art level.SOLUTION: An anhydrous composition is provided, which comprises: at least one saturated or unsaturated epoxy modified polyester as a binder; at least one acrylate or polyurethane polymer as another binder; polymer microparticles; at least one polymer containing a functional group made of a blocked isocyanate and an aminoplasto resin, as a crosslinking agent; at least one pigment; and at least one organic solvent and at least one auxiliary agent or additive. The solid content of the composition is at least 50 mass%.SELECTED DRAWING: None
