A sol-gel coating material, containing (A) an acrylate copolymer solution, consisting of at least one acrylate copolymer; (B) a parent lacquer which can be produced by the hydrolysis and condensation of at least one hydrolysable silane of the formula (I): SiR ; wherein: R&equals;hydrolysable groups, hydroxy groups and non-hydrolysable groups, with the proviso that there should be at least one hydrolysable group; and (C) a sol which can be produced by the hydrolysis, condensation and complexing of (C1) at least one hydrolysable metal compound of the (II): MR ; wherein: M&equals;aluminium, titanium or zirconium, R&equals;the aforementioned given groups and n&equals;3 or 4; of (C2) at least one organic thio compound of the formula (III): S(R X) , wherein R represents a two-bond organic radical and X represents hydroxyl, thiol and/or primary and/or secondary amino groups; and of (C3) a hydrolysable silane of the general formula (I).

Sol-gel coating

Powder clearcoat dispersions (powder slurry clearcoats) preparable by dispersing a powder clearcoat in an aqueous medium and wet milling the resulting powder slurry, at least one adduct of ethylene oxide and/or propylene oxide with at least one glycol being added to the powder slurry prior to wet milling; and the use of the powder slurry clearcoats for producing clearcoat finishes, especially as part of multicoat color and/or effect finishes.

Powder clearcoat dispersions (powder slurry clearcoats), method for producing them and the use thereof

The invention relates to a sol-gel coating material, containing (A) an acrylate copolymer solution, consisting of at least one acrylate copolymer (A1), (B) a sol which can be produced by the hydrolysis, condensation and complexing of at least one hydrolysable metal compound (B1) of the dormula (1): MR ; wherein the variable and the index have the following meanings: M&equals;aluminium, titanium or zirconium; R&equals;hydrolysable group, hydroxy groups and non-hydrolysable groups, with the proviso that there should be at least one, preferable two hydrolysable groups; and n&equals;3 or 4; by the hydrolysis, condensation and complexing of at least one hydrolysable silane (B2) of the formula (II): Si(R ) (R ) ; wherein the varible R and R have the following meanings: R &equals;alkyl and/or cycloalkyl radicals and R &equals;alkoxy and/or cycloakoxy radicals; and by the hydrolysis, condensation and complexing of at least one hydrollysable silane (B3) of the formula (III): SiR ; wherein the variable R has the aforementioned given meaning: with the proviso that the silane (B3) is not a silane (B2) according to the general formula (II); and (C) between 0 and 40% by weight in relation to the total quantity of the coating material, of a parent lacquer which can be produced by the hydrolysis and condensation of least one hydrolysable silane (B3) of general formula (III).

Aqueous coating substances for imparting a color and/or effect and use thereof for producing deformable laminates for imparting a color and/or effect

Polyurethane resin, method for the production and use thereof in an aqueous dual component clear varnish

The invention relates to a coating agent containing a) one or more polyester resins (A); b) one or more polyacrylate resins (B); c) one or more di- and/or polyisocyanates (C) with free or blocked isocyanate groups; d) one or more light stabilizers (L1) based on a UV absorber; e) one or more light stabilizers (L2) based on sterically hindered amines; and f) one or more organic solvents (D). The coating agent is characterized in that 1) the polyester (A) has a hydroxyl number of 80-200 mg KOH/g and an acid number <10mg KOH/g; 2) the polyacrylate resin (B) has a hydroxyl number of 80-200 mg KOH/g and an acid number <20 mg KOH/g; and 3) the light stabilizer (L2) based on sterically hindered amines is functionalized by aminoether.
