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

The description relates to physically drying water-based coating agents. They contain water, metallic pigments, optional other pigments, neutralizing agents, conventional additives, small proportions of solvents and a binder mixture consisting of

Water-based physically drying coating agents, manufacture and use thereof

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

Previous two-component coatings with enamine components cured very slowly at low temperatures and led to yellowed products. A binder composition is prepared which cures rapidly at low temperatures and leads to non-yellowing products. It contains as CH-acid component a polymer with at least two enamine functions in the molecule, obtained by

Binder composition and its use in surface coatings

A binding-agent composition for solvent-based or aqueous coating agents can be cured at low temperature to produce coatings which are non-yellowing and resistant to solvents. The binding-agent composition contains binding-agent components based on polyethers, polyesters, polyether polyesters and/or (meth)acrylic copolymers with, in each case, at least one acryloyl group and at least one epoxide group in the molecule, whereby the acryloyl groups and epoxide groups are present in the ratio 2:8 to 8:2. Also included are several polyamines as curing agents in a proportion of equivalent weights ranging from 2:0.5 to 1:1.5. The binding agents are used in pigmented and pigment-free lacquers, for use particularly in multi-layer lacquering.

Binding-agent composition, its production, coating agent containing said

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.

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.
