A powder paint composition. The powder paint composition contains (a) at least one polymer powder which can be re-dispersed in water, (b) pigment and filler, and optionally (c) which may be one or more adjuvants and/or may be one or more hydraulic binders. The at least one polymer powder which can be re-dispersed in water contains a polyvinyl alcohol-stabilized copolymer that is based on (a1) a wt % of a vinyl acetate, (a2) a wt % of ethylene and optionally (a3) and/or (a4) wherein (a3) is vinyl esters of long-chain, optionally branched Cto Ccarboxylic acids and (a4) is further ethylenically unsaturated comonomers that are co-polymerizable therewith.

Powder paint composition which can be redispersed in water

The invention relates to a composite heat insulation system, comprising an insulating layer, optionally a reinforcing layer, which is applied to the insulating layer, and a cover layer, which is applied to the insulating layer or, if present, to the reinforcing layer, characterized in that the cover layer contains composite particles, wherein the composite particles contain at least one organic polymer and at least one inorganic solid, wherein the weight percentage of inorganic solid is 15 to 40 wt %, with respect to the total weight of organic polymer and inorganic solid in the composite particle.

Composite heat insulation system

Insulating plasters and insulated molded panels produced by molding without input of heat contain closed or open celled light weight bodies or mixtures thereof, and at least one binder composed of composite particles containing both an organic polymer and from 15 to 50 weight percent of inorganic solid.

Porous molded body in the form of an insulating plaster layer or an insulating panel

The invention relates to aqueous preparations of polymer-modified setting accelerators, said preparations being characterized in that at least one setting accelerator and at least one cationically stabilized polymer are contained therein.

Aqueous preparations of polymer-modified setting accelerators, and use thereof in the construction industry

The invention relates to acid-resistant, hydraulically setting masses based on a) slag sand, b) one or more pozzolanas, c) one or more fillers, d) one or more polymers based on ethylenically unsaturated monomers, and water.

Acid-resistant, hydraulically setting masses

Functionalized copolymers hydrophobicized with silicones, in the form of aqueous dispersions or water-redispersible powders are prepared by copolymerizing

Solvent free coating compositions for soiling-resist ant facades

The invention relates to thickeners based on fully or partially hydrolyzed vinyl alcohol copolymers with a molecular weight Mw greater than 100,000, obtainable by hydrolyzing vinyl acetate copolymers which, besides vinyl acetate units, also contain comonomer units which derive from one or more comonomers selected from the group consisting of 1-(C )-alkylvinyl esters of C carboxylic acids, allyl esters, vinyl esters of alpha-branched C carboxylic acids, and C -alkyl (meth)acrylates, in the form of their aqueous solution or in powder form.

Thickeners based on vinyl alcohol copolymers

The invention relates to a fast-drying rendering and coating composition comprising a binder in the form of an aqueous polymer dispersion or of a water-redispersible polymer powder, and also an organic precipitant, if desired in combination with an inorganic precipitant.

Fast-drying rendering and coating composition

The invention provides a redispersible polymer powder based on a mixture of water-insoluble polymer and a water-soluble atomized protective colloid which can be de-activated through a pH change. In addition, the invention concerns aqueous dispersions that can be prepared with the polymer powder and the use of the polymer powder or its aqueous dispersions as a bonding agent in adhesives, plasters or paints.

Re-dispersible polymer powder and aqueous polymer dispersions obtainable therefrom

A process is provided for preparing crosslinkable binders in the form of the aqueous dispersions by polymerizing vinyl ester-olefin copolymers in the presence of protective colloid, which comprises polymerizing vinyl ester-olefin copolymers having a Tg of less than &minus;10&deg; C. by emulsion polymerization in the presence of a protective colloid based on (meth)acrylate polymers comprising from 80 to 95% by weight, based on the overall weight of the polymer, of acrylates or methacrylates of aliphatic alcohols of 1 to 12 carbon atoms and from 5 to 20% by weight, based on the overall weight of the copolymer, of ethylenically unsaturated monocarboxylic or dicarboxylic acids, the latter copolymer having a glass transition temperature Tg of from 60 to 120&deg; C., and, after the end of polymerization, introducing the crosslinkable groups by reacting the carboxyl groups of the (meth)acrylate polymers with ethylenically unsaturated compounds comprising functions suitable for esterifying the carboxyl group.
