A non-aqueous dispersion containing, in addition to organic solvents,

Hydroxyl group containing binder, a process for its preparation, and its

A transparent coating agent which is free of heavy metal catalysts and which contains a hydroxy functional (meth)acrylic copolymer based binder, an aliphatic or cycloaliphatic polyisocyanate crosslinking agent, a solvent, and lacquer adjuvant.

Coating agents, process for their preparation and their use for the

Coating composition containing one or several (meth)acrylic copolymers having hydroxyl groups, as well as one or several solvents and, optionally, water, special-effect pigments and/or coloring pigments, fillers and/or conventional lacquering additives, whereby the (meth)acrylic copolymer is essentially constructed from units based on the following monomers:

Coating composition and the use thereof in processes for producing

A coating material is described which exhibits high resistance to chemicals and is emulsifier-free. The coating material is useful as a lacquer layer coating on metallic substates such as automobiles. The coating material is based upon a polyester oligomer/polyacrylate wherein the polyacrylate contains hydrophilic and hydrophobic portions and the polyester contains hydroxyl functions. Capped polyisocyanates are also included in the coating material.

Emulsifier-free, heat-curable coating material, its preparation and use

A binding-agent composition for coating agents which can be cured at low temperature contains:

Binding-agent composition, coating agent containing said binding agent,

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.
