This invention relates to aqueous, crosslinkable binder dispersions which have a low solvent content and contain hydroxy-functional polyethers, hydroxy-functional acrylate copolymers and hydroxy- and carboxy-functional acrylate copolymers, to a process for the production of these binders, to one and two-component binder compositions containing these binders and to the use of the binder compositions in coating compositions.

Aqueous, crosslinkable binder dispersions having a low solvent content

The present invention relates to a process for preparing aqueous binders for aqueous coating compositions by reacting a mixture of

Aqueous binders and their use in aqueous coating compositions

The present invention relates to aqueous polyesters for high-solids stoving coatings which contain

Aqueous polyesters, a process for their production and their use in

This invention relates to an aqueous coating composition containing aluminum pigments and a water dispersible polyurethane polyurea binder which contains

Aqueous coating compositions containing water dispersible polyurethane

A coating is obtained on a substrate by applying to the substrate a composition containing as a binder an unsaturated polyester and hardening the coating by infra-red radiation, wherein the binder is a monomer-free olefinically unsaturated polyester resin having a viscosity of 2,000 to 5,000 mPa.s at 23.degree. C. and consists essentially of the esterification reaction product of:

Process for the production of coatings based on unsaturated polyester

The new 1,7,9,15-tetraoxa-4,12-diaza-8-silaspiro-[7.7]-pentadecanes, which are prepared by reaction of corresponding alkoxysilanes with corresponding alkanolamines, are used above all as hardening accelerators for unsaturated polyester resins and acrylic resins.

1,7,9,15-Tetraoxa-4,12-diaza-8-silaspiro-(7.7)-pentadecanes, a process

The present invention relates to a process for the production of water- and solvent-resistant coatings by coating substrates with an aqueous coating composition containing as binder a mixture of

Process for the production of sheet structures

The present invention is directed to a process for the production of water- and solvent-resistant coated substrates by coating heat-resistant substrates with a solution or dispersion of an anionic group-containing polyisocyanate addition product in an aqueous solvent or dispersant and subsequently thermally treating the coating at a temperature of about 60.degree. to 200.degree. C., with evaporation or vaporization of the solvent or dispersant and simultaneous crosslinking of the polyisocyanate addition product which has been applied to the substrate, characterized in that incorporated anionic structural units corresponding to the formula ##STR1## are used in a quantity of about 5 to 1000 milliequivalents per 100 g of solids and the solids are based on reaction products of organic polyisocyanates with salts of cyanamide and bases selected from ammonia, primary and secondary amines having a minimum pKb value of 3.1, tertiary amines and mixtures thereof. The present invention also relates to the aqueous solutions or dispersions of anionically-modified polyisocyanate addition products.
