The present invention relates to a process for producing single-coat or multicoat clearcoat finishes on primed or unprimed substrates by applying at least one powder coating dispersion, in particular a powder clearcoat slurry, to the substrate and then curing the resulting film(s) thermally and/or with actinic radiation, in which oxalic acid is added to at least one powder coating dispersion, in particular to a powder clearcoat slurry.

Low-yellowing aqueous clear powder coating dispersions, method of making the dispersions, and process for producing clearcoat finishes with the dispersions

The invention relates to an intrinsically viscous powder-slurry that can hardened by actinic radiation or optionally by thermal means, which contains solid spherical particles with an average particle size of 0.8 to 20 &mgr;m and a maximum particle size of 30 &mgr;m. The clear powder coating slurry contains 0.05 to 1 meq/g of ion-forming groups and 0.05 to 1 meq/g of neutralizing agents and has a viscosity of (i) 50 to 1000 mPas at a shear rate of 1000 s , (ii) 150 to 8000 mPas at a shear rate of 10 s , and (iii) from 180 to 12000 mPas at a shear rate of 1 s .

Powder-slurry that can be hardened by actinic radiation or optionally by thermal means, method for producing said slurry and use of the same

A pseudoplastic powder clearcoat slurry which is free from organic solvents and external emulsifiers and comprises solid spherical particles with an average size of from 0.8 to 20 &mgr;m and a maximum size of 30 &mgr;m, at least one ionic thickener and at least one nonionic associative thickener, the powder clearcoat slurry having an ion-forming group content of from 0.05 to 1 meq/g, a neutralizing agent content of from 0.05 to 1 meq/g, and a viscosity of (i) from 50 to 1 500 mPas at a shear rate of 1 000 s , (ii) from 150 to 8 000 mPas at a shear rate of 10 s , and (iii) from 180 to 12 000 mPas at a shear rate of 1 s .

Intrinsically viscous clear powder coating slurry which is free of organic solvents and external emulsifiers, method for producing said slurry and use of the same

Novel powder clearcoat materials and novel powder clearcoat slurries comprising a) at least one epoxide-containing binder containing from 0.5 to 40% by weight, based on the binder, of copolymerized glycidyl-containing monomers, and b) at least one tris(alkoxy-carbonylamino)triazine and at least one polycarboxylic acid, in particular a straight-chain dicarboxylic acid, and/or a carboxy-functional polyester as crosslinking agent, or alternatively a) at least one tris(alkoxy-carbonylamino)triazine and at least one oligomeric or polymeric, epoxide-containing crosslinking agent containing from 0.5 to 40% by weight, based on the crosslinking agent, of copolymerized glycidyl-containing monomers, and/or a low molecular mass, epoxide-containing crosslinking agent, and b) at least one carboxyl-containing polymer as binder, both variants comprising c) at least one polyol.

Powder clear varnish and aqueous powder clear varnish slurry

The present invention relates to a process for producing single-coat or multicoat clearcoat finishes on primed or unprimed substrates by applying at least one powder coating dispersion, in particular a powder clearcoat slurry, to the substrate and then curing the resulting film(s) thermally and/or with actinic radiation, in which at least one polyvalent inorganic acid and/or oxalic acid are or is added to at least one powder coating dispersion, in particular to a powder clearcoat slurry.

The present invention relates to an aqueous dispersion comprising a solid pulverulent component A and an aqueous component B, said component A comprising a UV-curable powder coating material.

Aqueous dispersion of transparent powder coating material

The present invention relates to a method of coating substrates, preferably of metal, by cleaning the substrate surface, applying, if desired, an organic and/or inorganic pretreatment composition, applying a primer, applying a coating material by spraying, dipping, knifecoating, rollercoating or brushing, the coating material comprising an amine-modified epoxy resin and a crosslinking agent suitable for crosslinking.

Method for coating substrates, preferably of metal

Aqueous binding agent dispersion for cationic electro-dipcoat paint

Water-dispersible epoxy resins modified with vinyl acetate copolymers

The invention relates to aqueous dispersions. They are obtainable by polymerizing an ethylenically unsaturated monomer or a mixture of ethylenically unsaturated monmers &lsqb;sic&rsqb; in an aqueous solution of an at least partially protonated epoxide-amine adduct. It is characterized in that the epoxide-amine adduct is for its part obtainable by reacting (A) a glycidyl ether of a polyphenol that contains on statistical average at least one epoxide group in the molecule, or a mixture of such glycidyl ethers, (B) a polygycidyl &lsqb;sic&rsqb; ether of a polyol that contains on statistical average more than 1.0 epoxide groups in the molecule, or a mixture of such polyglycidyl ethers, and (C) a compound that contains a primary amino group in the molecule, or a mixture of such compounds, to give the epoxide-amine adduct, components (A) and (B) being employed in a ratio of equivalents of from 1.0:0.5 to 1.0:8.0 and from 0.3 to 0.7 mol of component (C) being employed per equivalent of epoxide groups of (A) and (B).

Dispersion product for producting an electrophoretically precipitable dipping varnish

The present invention relates to an electrodepositable coating composition comprising binders, pigments, fillers, corrosion protection inhibitors, paint auxiliaries, catalysts if desired, organic solvents and water, which additionally comprises an organic amine salt.
