Coating installations are provided that include storage tanks for an aqueous base component and a non-aqueous hardener component, circulation lines for the components from the respective storage tanks, a mixer and an entrance to the mixer with a connection between each circulating line and the entrance to the mixer, and a release valve for the non-aqueous hardener component. The coating installation downstream of the non-aqueous hardener release valve is filled with a non-aqueous solvent composition comprising 0 to 10 wt. % of N-alkyl pyrrolidone, 0 to 5 wt. % of dimethyl sulfoxide, 10 to 50 wt. % of &#x3b3;-butyrolactone, 10 to 50 wt. % of at least one monoalcohol, 10 to 60 wt. % of at least one organic solvent inert towards isocyanate groups, other than &#x3b3;-butyrolactone, other than N-alkyl pyrrolidone, and consisting of carbon, hydrogen, oxygen and, optionally, nitrogen, and 0 to 10 wt. % of at least one additive.

Coating installation of an industrial mass production coating line including non-aqueous solvent composition as barrier liquid

A process for the production of a multi-layer coating includes applying a coating layer from an aqueous pigmented coating composition A onto a substrate provided with an EDC primer and applying a base coat layer from an aqueous coating composition B overlying the coating layer. A clear coat layer is applied onto the base coat layer and the three coating layers are jointly bake-cured. The coating compositions A and B are different from each other and coating composition A comprises (i) binder solids, (ii) free polyisocyanate, (iii) a pigment content free of special effect pigments and comprising carbon black pigment and/or titanium dioxide pigment, and (iv) talcum filler.

Process for the production of a multi-layer coating

A process for the production of multi-layer coatings comprising the successive steps: 1) applying an 8 to 20 &#x3bc;m thick coating layer from an aqueous coating composition A onto a substrate provided with an EDC primer, 2) applying a 5 to 15 &#x3bc;m thick base coat layer from an aqueous coating composition B onto the previously applied coating layer, 3) applying a clear coat layer onto the base coat layer, 4) jointly curing the three coating layers, wherein coating compositions A and B being different from each other and wherein the coating composition A contains at least one metal platelet pigment having a thickness from 10 to 100 nm in a proportion corresponding to a pigment/resin solids ratio by weight from 0.06:1 to 0.2:1.

Process for the production of multi-layer coatings

A process for the production of multi-layer coatings in A' color shades, comprising the successive steps: wherein the base coat layer is applied in a first layer of a modified water-borne base coat modAB prepared by mixing an unmodified, water-borne base coat A with an unmodified water-borne base coat B and with a pigment-free admixture component and in a second layer of the unmodified water-borne base coat A.

The present invention is a process for producing multilayer coatings. The present invention is a process for the production of coatings having a low total coating thickness in the desired color shade without separate baking of the primer surfacer layer.
