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.

Process for curing surface-coating compositions

Disclosed are alkyd resin emulsions for coating varnishes, containing a water-insoluble alkyd resin A and a water-soluble alkyd resin B that is used as an emulsifying resin and represents an esterification product of an alkyd resin Ba which can be homogeneously mixed with the alkyd resin A at a weight ratio (Ba to A) ranging between 2:98 and 50:50, alkyd resin A being the resin that is to be emulsified, and an adduct Bb of a C-Calkoxy polyethylene glycol Bba and a cycloaliphatic dicarboxylic acid anhydride Bbb at a mole ration (Bba to Bbb) ranging between 09.95:1.05 mol/mol and 1.05:0.95 mol/mol. Also disclosed is a method for the production thereof, the use thereof for coating substrates selected among textiles, mineral materials, metals, and wood.

Alkyd resin emulsions for coating varnishes

A water-soluble or water-dispersible polyester B useful as emulsifier for aqueous emulsions of alkyd resins A, wherein the polyester B is obtainable by reacting, under polycondensation conditions, polyhydroxyl components Ba from the class of the sugar alcohols having more than 4 carbon atoms and at least five hydroxyl groups per molecule, alkoxypolyethylene glycols Bb having 1 to 4 carbon atoms in the alkyl radical and a number-average molar mass M of from 500 to 2000 g/mol, cycloaliphatic dicarboxylic acids Bc and unsaturated or saturated fatty acids Bd having 10 to 22 carbon atoms, a process for its preparation, and alkyd resin emulsions prepared therewith.
