Abstract: A new flatting agent for self-curing or radiation-curing coating systems is disclosed. The flatting agent is a liquid dimerdiol (meth)acrylate with a degree of esterification of at least 50%. The dimerdiol (meth)acrylate ester is introduced into the coating system in an amount of 1-25% by weight based on the coating system as a whole. The coating system can have additional solid flatting agents in the system.

Abstract: The disclosed invention relates to mixtures of acrylic or methacrylic compounds containing 1 to 35% by weight and, more particularly, 5 to 25% by weight epoxy (meth)acrylates, based on the total quantity of acrylic or methacrylic compounds, the mixture being obtainable by a process comprising the following steps: a) esterifying hydroxyl compounds with acrylic acid and/or methacrylic acid, b) optionally adding more acrylic acid and/or methacrylic acid and c) reacting the excess acrylic acid and/or methacrylic acid with epoxides in the presence of the esterification product of a). Said mixtures are suitable for use as radiation-curable compositions for coating systems, such as paints, coating compositions and the like.
