This invention relates to copolymers AB having moieties derived from vinyl-terminated polysiloxanes A with more than one vinyl group bound to the polysiloxane, and moieties derived from two or more alkyl esters B of an olefinically unsaturated carboxylic acid, wherein at least two different alkyl esters B1 and B2 are used; the alkyl group of the first alkyl ester B1 of an olefinically unsaturated carboxylic acid has from one to five carbon atoms, the alkyl group of the second alkyl ester B2 of an olefinically unsaturated carboxylic acid has from six to thirty carbon atoms, and moieties derived from at least one hydroxyalkyl ester B3 of an olefinically unsaturated carboxylic acid, the ester B3 having at least one hydroxyl group in the alkyl group, and from two to six carbon atoms in the alkyl group, to a process for their preparation, and to a method of use thereof as flow modifiers in coating compositions.

Flow modifiers for coating compositions

The invention relates to a paste resin A which is a mixture of at least two acrylic copolymer resins A, wherein the acrylic copolymer resin A1 comprises at least one basic acrylic comonomer, and the acrylic copolymer resin A2 comprises at least one acidic acrylic comonomer, and a method of use thereof for formulating both water-borne and solvent-borne tinted paints with a wide variety of pigments.

Paste resin

The present invention relates to a method for coating surfaces by applying an oxidatively drying coating composition comprising at least one oxidatively drying binder and at least one drying agent acting as an accelerator of the drying and curing process proceeding under the action of an oxidizing agent, characterized in that the drying agent comprises at least one oxidoreductase and at least one mediator which is converted by the at least one oxidoreductase.
