AQUEOUS COATING COMPOSITIONS BASED ON ACRYLATE COPOLYMERS |
摘要 |
The invention is directed to aqueous coating composition comprising A) at least one water-dilutable (meth)acrylate copolymer and B) at least one polyisocyanate cross-linking agent with free isocyanate groups, wherein the (meth)acrylate copolymer comprise a) 10-80% by weight of at least one reaction product of a monoepoxyester and an unsaturated acid functional monomer b) 0-40% by weight of at least one hydroxy functional unsaturated monomer which is different from component a), c) 1-8% by weight of at least one unsaturated acid functional monomer and d) 0-70% by weight of at least one other polymerisable unsaturated monomer, wherein the% by weight of components A) and B) and of components a) to d) is adding up to 100% by weight and wherein the (meth)acrylate copolymer is prepared by a skew feed polymerization process with at least two feed streams and wherein one feed stream comprises the main quantity, namely 60-100% by weight of component a), based on the total amount of component a) and the lower amount, namely 0-30% by weight of the unsaturated acid functional monomer c) based on the total amount of monomer c).
