The use of a composition which is liquid under standard conditions (20&#xb0; C., 1 bar) as a coating material, wherein the composition comprises

Coating material comprising unsaturated polyester resins and vinyl ethers

A thermosetting transparent coating material, its preparation and use. The coating includes (meth)acrylate (co)polymer having a number-average molecular weight of from 1,000 to 6,000 daltons, a glass transition temperature of &#x2212;15 to +70&#xb0; C., and a hydroxyl number of from 80 to 200 mg KOH/g; polyester having a number-average molecular weight of from 800 to 6,000 daltons, a hydroxyl number of from 80 to 200 mg KOH/g and an acid number of from 1 to 50 mg KOH/g, comprising, based on the polyester, from 30 to 70% by weight of cycloaliphatic structural units; a blocked polyisocyanate in which the blocked polyisocyanate groups are attached to flexibilizing structural units which, as part of a three-dimensional network, lower its glass transition temperature; and blocked polyisocyanate in which the blocked polyisocyanate groups are attached to hardening structural units which, as part of a three-dimensional network, raise its glass transition temperature.

Coating agent with a macromer unit for the production of multi-layered coatings

The invention relates to nonaqueous coatings containing a polyacrylate resin and a urea group-containing thixotropic agent and having improved surface properties. The polyacrylate resin is prepared by polymerizing (a) from 16 to 51% by weight of a hydroxyl group-containing ester of acrylic acid or methacrylic acid or of a mixture of such monomers; (b)from 32 to 84% by weight of an aliphatic or cycloaliphatic ester of acrylic acid or methacrylic acid which is different from (a) and has at least 4 carbon atoms in the alcohol radical or of a mixture of such monomers; (c) from 0 to 2% by weight of an ethylenically unsaturated carboxylic acid or of a mixture of ethylenically unsaturated carboxylic acids, and (d)from 0 to 30% by weight of an ethylenically unsaturated monomer which is different from (a), (b) and (c) or of a mixture of such monomers. The polyacrylate resin has an acid number of from 0 to 15, a hydroxyl number of from 80 to 140, and a number-average molecular weight of from 1,500 to 10,000, the sum of the proportions by weight of components (a), (b), (c) and (d) always being 100% by weight. The urea group containing thixotropic agent is prepared by reacting a compound selected from the group consisting of polyisocyanates and mixtures thereof, with an aliphatic monoamine selected from the group consisting of primary amines, secondary amines, water, and mixtures thereof, in the presence of the polyacrylate resin, to form a dispersion of the urea group containing thixotropic agent and the polyacrylate resin.

Nonaqueous coating and process for producing a two-coat finish

Aqueous solutions or dispersions of binders for preparing aqueous coating materials are produced, including as an aqueous component water of reaction which is obtained during the condensation of alcohols with carboxylic acids.

Aqueous binder solutions and dispersions

The present invention relates to coating materials with hydroxyl-containing polymers and di- and/or polyisocyanates, at least some of whose isocyanate groups are blocked with a mixture of from 30 to 85% by weight of one or more dialkyl malonates in which at least one of the ester radicals is an aliphatic, cycloaliphatic and/or araliphatic secondary alkyl radical having at least 3 carbon atoms and 70 to 15% by weight of at least one other dialkyl malonate. Preparation and the blocked polyisocyanates and coating materials and use of the coating materials is also provided.
