    摘要： A coating composition includes a flexible hyperbranched polyol preparable by (a) reacting a polyol comprising at least three hydroxyl groups with an aliphatic dicarboxylic acid having from 6 to 36 carbon atoms or an esterifiable derivative of the aliphatic dicarboxylic acid to form a hydroxyl-functional first intermediate product; (b) reacting the first intermediate product with a cyclic carboxylic acid anhydride to form a carboxylic acid-functional second intermediate product; and (c) reacting the second intermediate product with an epoxide-functional compound having one epoxide group to form the hyperbranched polyol. The coating composition may be cured to a coating layer having excellent flexibility.

    摘要： Described herein is a coating composition including (A) a physically curing, reactively self-curing and/or externally curing component, including, based on a total solids content of component (A), from 0.1% by weight to about 2.5% by weight of a branched polyester polyol, preparable by: (a) reacting a polyol including at least three hydroxyl groups with an aliphatic dicarboxylic acid having from 6 to 36 carbon atoms or an esterifiable derivative of the aliphatic dicarboxylic acid to form a hydroxyl-functional first intermediate product; (b) reacting the first intermediate product with a cyclic carboxylic acid anhydride to form a carboxylic acid-functional second intermediate product; and (c) reacting the second intermediate product with an epoxide-functional compound having one epoxide group to form the branched polyester polyol; and (B) a crosslinking component in case component (A) includes one or more externally curing components; and optionally (C), a diluent component.

    摘要： Disclosed herein is a clearcoat coating material composition including an OH-functional (meth)acrylic copolymer (A1), a branched OH-functional polyester (A2) in an amount in the range of from 1.0 wt.-% to 15.0 wt.-%, based on the total solids content of the coating material composition, and at least one crosslinking agent (B1), which is different from both constituents (A1) and (A2) and which contains crosslinkable functional groups, which can be crosslinked with OH-functional groups. Further disclosed herein are a method of coating a substrate including applying to an optionally pre-coated substrate the inventive clearcoat coating material composition, a coated substrate, which is obtainable by the disclosed method, and a method of using the branched OH-functional polyester (A2) as flow enhancer in a clearcoat coating material application for spray applying said clearcoat coating material application onto an optionally pre-coated substrate and/or as levelling agent.
