Pastes containing matting and structuring agents and coating agents containing said pastes

This invention relates to copolymers which contain hydroxyl groups and which are based on vinyl esters of monocarboxylic acids, wherein the copolymers which contain hydroxyl groups have an OH number of 110-170 mg KOH/g, an acid number of 5-35 mg KOH/g and a number average molecular weight M.sub.n of 1500-8000 g/mole and are obtainable by the polymerisation of A) 5-20% by weight of one or more vinyl esters of saturated monocarboxylic acids, B) 10-30% by weight of one or more aromatic vinyl hydrocarbons, C) 41-55% by weight of hydroxy-functional, polymerisable, unsaturated monomers, and D) 0-40% by weight of further polymerisable, unsaturated monomers, wherein component C) contains C1) 40-70% by weight of one or more hydroxyalkyl esters of .alpha.,.beta.-unsaturated monocarboxylic acids, C2) 1-10% by weight of one or more lactones, and C3) 30-55% by weight of one or more reaction products of an .alpha.,.beta.-unsaturated monocarboxylic acid with a glycidyl ester of a saturated .alpha.,.alpha.-dialkylalkane-monocarboxylic acid or of a saturated .alpha.-alkylalkane-monocarboxylic acid, and the sum of components A) to D) and the sum of components C1) to C3) add up to 100% by weight in each case.

Copolymers which contain hydroxyl groups and a method of producing them

This invention relates to coating media based on one or more styrene-free, unsaturated polyester resins, which contain

Coating medium, a method of producing multi-layer coatings and the use

This invention relates to two-component, solvent-thinnable coating media based on a polyisocyanate component and a component which reacts with isocyanate. The coating media contain one or more hydroxy-functional copolymers, one or more secondary polyamines containing ester groups, one or more aliphatic and/or cycloaliphatic polyisocyanates containing allophanate groups, extenders and/or pigments and optionally one or more organic solvents and customary lacquer additives. 60 to 75% by weight of aluminium hydroxide and calcium magnesium carbonate are contained in total, with respect to the total amount of extenders and/or pigments.

Coating media and a process for producing multi-layer coatings

Coating agents are described, that are suitable for the production of pigmented or transparent top coatings, based on hydroxy-functional (meth)acrylic copolymers, aliphatic and/or cycloaliphatic polyisocyanates, solvents, and customary lacquer additives and pigments. They are free from epoxy resins and nitrocellulose and contain as binder

Coating agents and their use in particular in the production of

The description relates to coating agents for use as primers and fillers in the manufacture of multilayer lacquer coatings, more particularly in the motor-vehicle sector. The coating agent contains a binder mixture of

Coating agents and use thereof as primers and/or fillers in the

Process for cleaning equipment and equipment cleaner for implementing the process. The invention relates to a process for cleaning equipment contaminated with lacquer residues, in which the lacquer residues are removed with a solvent mixture and an equipment cleaner based on a solvent mixture for implementing the process. The solvent mixture contains

Process for cleaning water and organic solvent based lacquer from

A coating medium suitable for multilayer coatings, containing A) copolymers containing hydroxyl groups, comprising

Coating medium, the use thereof, and a process for multilayer coating

A binder composition for coating agents contains

.beta.-keto-ester-esterified polyol with polymerized monomers

Oligoester acrylate resins having a high content of solids and comparatively low viscosity, and aqueous coating agents with a low content of organic solvents for obtaining coatings with high resistance to chemicals, more particularly high resistance to acids and oily soot, and very low tendency to yellowing.

Emulsifier-free coating agent, manufacture and use thereof

A binder composition suitable for coating agents is described, that contains one or more unsaturated polyesters with an acid number of 5-60 mg KOH/g, a hydroxyl number of 50-200 mg KOH/g and a weight-average molecular weight (Mw) of 500-3000 g/mol, that are obtainable by reaction of

Binder and coating agent composition, its manufacture and use

A coating and primer composition suitable as a primer for plastics such as a polyolefin which comprises: a) from about 1 to 5% by weight of ethylene/vinyl acetate copolymers, b) from about 0.5 to 5% by weight of chlorinated polyolefins, c) from about 0.01 to 5% by weight of an epoxy resin; and d) from about 85 to 98.49% by weight of an organic solvent, and optionally paint auxiliaries, pigments and/or fillers. A method of priming plastic surfaces of an object, especially polyolefins, and particularly polypropylene, is also provided which comprises applying the aforesaid composition to a plastic surface and drying the same prior to applying paint or finish coating.

Plastic primer coating of eva, chlorinated polyolefin and epoxy resin

Binder, process for its preparation and its use in clear or pigmented

Previous coating materials lead to the formation of bubbles at high layer thickness and when drying by heating. The new coating materials are intended to be bubble-free when dried at higher layer thicknesses. Aside from pigments and/or extenders, the coating material contains solvents and, if necessary, conventional paint auxiliaries in a vehicle mixture, comprising essentially 60-75% by weight of a hydroxy-functional copolymer, 1-5% by weight of an ester-soluble nitrocellulose and 25-35% by weight of difunctional or multifunctional polyisocyanate. It can be cured without forming bubbles even when applied in thick layers. Use as primer and filler.
