    Abstract: Epoxy resin materials essentially contain (A) an epoxy resin having a mean molecular weight of from 300 to 6,000 and on average from 1.5 to 3.0 epoxy groups in the molecule and (B) a polyacrylate resin obtainable by polymerization of essentially (b1) from 30 to 95% by weight of esters of acrylic acid and/or methacrylic acid and/or ethylacrylic acid with C1-C20-alcohols in the presence of (b2) from 5 to 70% by weight of carboxyl-containing copolymers having a mean molecular weight of from 500 to 20,000, obtainable by bulk or solution polymerization and are used for heat-curable finishes, adhesive bonds and coatings.

    Abstract: A process for the production of coatings based on reaction products of (A) mixtures of (A1) polyhydroxypolyacrylate resins obtained from hydroxylalkyl esters of acrylic acid and/or methacrylic acid, alkyl esters of acrylic acid and/or methacrylic acid, and one or more polymerizable, olefinically unsaturated nitrogen-containing heterocyclic compounds, with or without vinylaromatics, (meth)acrylamides and other monomers, and (A2) polyesterpolyols with (B) isocyanurate-containing polyisocyanates which may or may not contain biuret groups, have a functionality of from 2.5 to 6 and possess predominantly cycloaliphatically bonded isocyanate groups, some of which may be replaced by aliphatically bonded isocyanate groups. The process is particularly useful for coating metal components.
