An aqueous effect coating material, comprising

Effect-producing, aqueous coating material, method for the production and use thereof

A wet-on-wet process for producing multicoat color and/or effect coating systems is disclosed. The process involves using aqueous functional coating materials comprising

Aqueous functional coating material and integrated method for production of coloured or effect-generating multi-layer coatings

Use of associative thickeners based on polyurethane and/or dipropylene glycol monoalkyl ethers for suppressing defects in color and/or effect multicoat paint systems, or their touch-up paints.

Use of associative thickeners based on polyurethane and/or dipropylene glycol monoalkyl ethers in colored and/or decorative effect multi-layered lacquers

The invention concerns a novel aqueous composition that can be hardened physically, thermally and/or with actinic radiation, containing a compound of general formula (I): X&lsqb;NH&mdash;C(&boxH;O)&mdash;NH&mdash;Y&mdash;NH&mdash;C(&boxH;O)&mdash;OR&rsqb;2 having at least one urea and urethane group, wherein the variables have the following meaning: R represents identical or different polyalkylene glycol ether radicals; X represents a bivalent substituted or unsubstituted arylene radical; Y represents identical bivalent substituted or unsubstituted arylene radicals, which are the same as or different from radical X or different bivalent substituted or unsubstituted arylene radicals of which none or one is identical to radical X. The invention also concerns the utilization of said compound for the production of novel aqueous coating materials, adhesives and sealants that can be hardened physically, thermally or thermally and with actinic radiation and their derivatives.

Aqueous composition that can be hardened physically, thermally or thermally and with actinic radiation and the derivatives and production thereof

Method for producing multilayer coatings

Aqueous lacquer containing a multicomponent aqueous dispersion

The present invention relates to an aqueous powder coating dispersion which can be prepared by processing the binder of the powder coating material and/or the crosslinker of the powder coating material or the entire powder coating material to give a powder by spray drying and then preparing an aqueous powder coating dispersion using the spray-dried powder. The present invention additionally relates to a process for preparing the aqueous powder coating dispersion and to the use of the powder coating dispersion, especially for the coating of automobile bodies.

Aqueous coating powder dispersion, method for the production and use of said dispersion

The use as an additive for coating formulations is claimed of a polymer dispersion which comprises (i) an acrylate polymer based on from 30 to 60% by weight of C,-C,-alkyl (meth)acrylate monomers, from 30 to 60% by weight of vinylaromatic monomers and from 0.5 to 10% by weight of (meth)acrylic acid, and (ii) a nonassociative rheology stabilizer comprising an acrylate copolymer based on C,-C,-alkyl (meth)acrylate and (meth)acrylic acid.
