Process for the production of a dark-color multi-layer coating

A process for the production of a dark-color multi-layer coating, comprising the successive steps: (1) applying an NIR-opaque coating layer A' from a waterborne pigmented coating composition A to a substrate, (2) applying a coating layer B&#x2032; from a waterborne pigmented coating composition B onto the substrate provided with coating layer A&#x2032;, (3) subjecting the coated substrate obtained in step (2) to a drying step, (4) applying a clear coat layer, and (5) curing the coating layers simultaneously; wherein both coating compositions A and B comprise aqueous microgel and sheet silicate, wherein the pigment content of coating composition A consists 90 to 100 wt. % of aluminum flake pigment and 0 to 10 wt. % of further pigment, wherein the pigment content of coating composition B consists 50 to 100 wt. % of black pigment with low NIR absorption and 0 to 50 wt. % of further pigment.

Non-aqueous, liquid coating compositions which contain at least one epoxy-functional binder A and at least one carboxyl-functional cross-linking resin B, wherein the at least one cross-linking resin B is present as particles having a melting temperature of 40 to 180&#xb0; C.

Process for the high-speed rotary application of liquid coating agents

Improved aqueous powder coat dispersion, comprising (a) a powder coating dispersed in (b) an aqueous phase, wherein the aqueous phase contains a silica compound selected from the group consisting of (i) 0.2 to 2% by weight, based on the weight of the powder coating, of finely divided silicic acid with large BET-surface; (ii) 0.1 to 1.5% by weight, based on the weight of the powder coating, of layered silicates; and (iii) combinations thereof, exhibit improved sedimentation properties and provide coatings with improved sag characteristics.

Aqueous powder coat dispersions, process for their preparation and their use

A process for preparing a multi-layer coating on an electrically conductive automotive body or an electrically conductive automotive body part by applying a cathodic electrodeposition coating layer, optionally a further coating layer and an outer clear coating, in which the cathodic electrodeposition coating layer of a cathodic electrodeposition coating composition is applied which, as the cathodic electrodeposition binder, contains a seed polymer with an amine value of 30 to 100 mg KOH/g and a hydroxyl value of 50 to 200 mg KOH/g, which can be prepared by radical polymerisation of 70 to 97 wt-% of a monomer mixture comprising hydroxy-functional olefinically unsaturated monomer and amino-functional olefinically unsaturated monomer in the presence of 3 to 30 wt-% of an aminoepoxy resin.
