A coating compound comprising a binder/crosslinking agent system that comprises 20 wt. % to 80 wt. % of one or more carboxyl-functional components A) and 80 wt. % to 20 wt. % of one or more epoxy-functional (meth)acrylic copolymers B).

Coating agents which can be used for multi-layer enameling

A base-neutralized, water-diluted coating comprises (A) a polyhydroxyl-functional resin of an acrylate resin or an oil-free polyester containing urethane groups, (B) an amino resin partially etherified with an alcohol, (C) a basic neutralizing agent, (D) water, and (E) a water-insoluble crosslinking catalyst of a strong organic or inorganic acid such as p-toluenesulfonic acid blocked with a monoepoxide, diepoxide or lactone.

Water-dilutable coating of oh-acrlylate or polyesterurethane resin and blocked acid catalyst

Transparent coating agents and the use thereof to produce multi-layered coatings

Binder vehicle and coating medium composition and the use thereof for multi-layer coating

A water-dilutable coating after base neutralization comprises a polyhydroxyl-functional resin including a condensation resin such as a polyester or alkyd resin, and/or a polyhydroxyl-functional addition resin such as an acrylate resin or the reaction product of a carboxyl-functional acrylate resin and a hydroxyl-functional acrylate resin, and/or an emulsion copolymer, an at least partially monoalcohol-etherified amino resin, and a strong organic or inorganic acid crosslinking catalyst non-ionically blocked with a monoepoxide, a diepoxide or a lactone.

Water-dilutable coating composition of polyhydroxyl condensation or addition resin, amino resin and blocked acid catalyst

Coating agent, the manufacture and uses thereof

Coating media, the use thereof, and a method of producing multilayer

A method of producing a multi-layer coating comprising the application of a color- and/or effect-imparting base lacquer coat of an aqueous base lacquer, the wet-into-wet-application on to the aqueous base lacquer coat of a clear lacquer coat of a two-component polyurethane clear lacquer, which is produced shortly before the application thereof by mixing a master lacquer component, which contains hydroxy-functional binder vehicles and solvents, with a polyisocyanate component, and joint stoving of the aqueous base lacquer and clear lacquer coats, wherein the two-component polyurethane clear lacquer which is used contains 0.01 to 1% by weight, with respect to the clear lacquer solids, of one or more additives with a surface tension-lowering effect, wherein at least 25% by weight of the additives with a surface tension-lowering effect is contained in the polyisocyanate hardener component before mixing.
