The present invention relates to aqueous binder compositions comprising an aqueous polymer latex of a film forming carboxylated polymer and a branched polyetheramine polyol dissolved in the aqueous phase of the aqueous polymer latex, wherein essentially all of the amino groups in the branched polyetheramine polyol are tertiary amine groups. The present invention also relates to water-borne coating compositions containing such an aqueous binder composition.

Aqueous binder compositions

The present invention provides the use of aqueous polymer dispersions comprising (a) at least two monomers M1 having a glass transition temperature &#x2265;25&#xb0; C., (b) at least two monomers M2 having a glass transition temperature &#x3c;25&#xb0; C., and also further monomers M3, as binders in coating materials for improving the shade stability (color retention).

Use of aqueous polymer dispersion in coating agents for improving colour retention

What are described are coating compositions comprising pigments and/or fillers and multistage polyvinyl ester dispersions as binders. These binders are produced by a selected multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form or in the form of an emulsion are added to the reaction mixture in a second stage and then the polymerization is started again. The polyvinyl ester dispersions comprise polymerized silanes and/or epoxides or the polyvinyl ester dispersions have only a small content of protective colloids, if any. The coating compositions formulated with the multistage polyvinyl ester dispersions obtained in this way are notable for a very high weathering resistance.

Coating compositions having high weathering resistance, process for preparation thereof and use thereof

What are described are polyvinyl ester dispersions which are prepared in a multistage process and have a low content of polymerized acids or acid anhydrides. They can be obtained by a multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form are added to the reaction mixture in a second stage and then the polymerization is started again. The polymer dispersions obtained in this way are notable for a low coagulum content and for increased tensile strengths of the films formed therefrom.

Polyvinyl ester dispersions, process for preparation thereof and use thereof

Plasters and renders and paints, copolymer dispersions and their use Compositions containing selected polymer dispersions, colloidal silica, fillers and pigments are described. These can be formulated to give plasters and renders or paints which are distinguished by excellent abrasion resistance, little tendency to soiling, high water vapor permeability, good adhesion and good weathering stability. The compositions according to the invention can be processed to give plasters and renders or paints which have a nanostructured surface and which differ from conventionally produced surfaces.

Plasters and renders and paints, copolymer dispersions and their use

Multistage polymers predominantly stabilized by nonionic emulsifiers and derived from hard and soft monomer compositions containing vinyl esters, of which at least one monomer composition must contain an unsaturated compromisable organosilicon compound, are described. The plastic dispersions can be used as binders in emulsion paints and finishes and impart to these excellent scrub resistance in addition to good blocking resistance.

Aqueous plastic dispersions, method for producing the same and their use

A description is given of coating compositions comprising at least one strongly basic agent to set a pH of at least 10, at least one selected vinyl ester copolymer, if desired, pigment and/or filler, and, if desired, further additives customary per se. The coating compositions can be stored without use of additional preservatives and can be used to coat substrates of all kinds.

Coating agents that are devoid of preservatives, method for their production and use thereof

A description is given of food coating compositions comprising The coatings are distinguished by sufficiently high water vapor transmission rates, low water absorption capacity and also low reemulsification capacity and have good mechanical properties in the moist state.

Food coating composition comprising protective colloid-stabilized polyacrylate dispersions, use thereof and coated foods produced therewith

The invention relates to water-dilutable binding agents and coating agents with particularly quick drying surfaces. The invention also relates to a method for the production and use thereof. The water-dilutable binding agents are based on polymer dispersions, which are characterized in that they contain at least one poly acid/polyvinylpyrrolidone complex and optionally one or several water-soluble zircon compounds. The inventive binding agents have a quick drying surface and are suitable for use in the production of primers, paints and plasters with quick drying surfaces or quick-acting wash-fastness.

Polymer complex coating agents, method for the production and use thereof

The invention relates to new rewettable adhesive systems containing colloidal dispersion mixtures obtained by copolymerization of at least one water-soluble monomer with at least one non-water-soluble comonomer in the presence of a micelle-forming emulsifier. The invention also relates to the use of the new adhesive systems.

Novel colloid dispersion mixtures as protective colloid for aqueous emulsion polymerization, processes for preparing them and their use. The present invention relates to novel colloid dispersion mixtures comprising a water-soluble monomer and a water-insoluble comonomer, to processes for their preparation and to their use as protective colloid for emulsion polymerization.

Colloid dispersion mixtures as protective colloid for aqueous emulsion

The present invention relates to a process for reducing the concentration of organometallic and/or inorganic by-products in product mixtures formed in the synthesis of metallocenes, which comprises treating a mixture comprising one or more metallocenes and one or more organometallic and/or inorganic by-products with a polar extractant.
