Aqueous multi-constituent coating material, method for the production thereof and use of the same

摘要

An aqueous multicomponent coating material comprising (I) an aqueous component preparable by mixing at least the following starting products: (A) at least one secondary aqueous dispersion of at least one (meth)acrylate copolymer containing on average per molecule at least one isocyanate-reactive functional group, (B) at least one primary aqueous dispersion of at least one (meth)acrylate copolymer containing no isocyanate-reactive functional group, and (C) at least one pigment and/or one filler; and also (II) a component comprising at least one polyisocyanate as crosslinking agent, and also a process for preparing it, and its use.
