COATING COMPOSITIONS AND COATINGS PRODUCED FROM THEM WITH HIGH SCRATCH RESISTANCE, WEATHERING STABILITY, AND GOOD OPTICAL PROPERTIES
摘要:
The invention relates to coating compositions comprising (a) at least one hydroxyl-containing compound (A), (b) at least one saturated compound (B) having free and/or blocked isocyanate groups and containing at least in part hydrolyzable silane groups, and (c) at least one catalyst (D) for the crosslinking of silane groups, wherein the coating composition comprises as hydroxyl-containing compound (A) at least one hyperbranched, dendritic hydroxy-functional polyester in which on average at least one hydroxyl function of the polyester is esterified with at least one acid selected from the group of the isomeric C8 to C9 monocarboxylic acids. The present invention also provides a multistage coating method using these coating compositions, and also the use of the coating compositions as clearcoat material for producing multicoat effect and/or color paint systems, and use of the coating method for automotive OEM finishing and automotive refinish.
