    Abstract: The present invention relates to a coating material formulation comprising a mixture comprising as component a1 at least one surfactant and as component a2 at least one compound corresponding to the general formula (I) R1-O-(CH2-CHR2-O)n-(CH2-CH2-O)m-R3 (I) in which R1 is phenyl or substituted phenyl, C4-C14 alkyl, R2 is C1-C8 alkyl, R3 is hydrogen, C1-C6 alkyl, benzoyl, acetyl, acryloyl, methacryloyl, n has an average value of 0 to 10, m has an average value of 1 to 10, where n+m n, and the alkylene oxide structural units, which are different if appropriate, can be distributed randomly or arranged in blocks, 1%-95% by weight of film-forming binders and resins, 0%-80% by weight of fillers, 0%-40% by weight of pigments, 0%-20% by weight of additives and 0%-90% by weight of organic solvents and/or water, the sum of the weight percentages being 100% by weight, and to the use of the mixture of the invention for lowering the surface tension in a coating material by addition to the coating material.

    Abstract: The present invention relates to a method for separating an at least one first substance from a mixture containing said first substance and at least a second substance, comprising the steps of: (A) bringing at least one magnetic particle and at least one bifunctional molecule, or an adduct of the two, into contact with the mixture containing the at least one first substance and at least a second substance so that an adduct is formed from the at least one magnetic particle, the bifunctional compound of the general formula (I) and the at least one first substance, (B) suspending the adduct obtained in step (A) in a suitable suspension agent, (C) separating the adduct present in the suspension of step (B) by applying a magnetic field, (D) optionally splitting the adduct separated in step (C) to obtain the at least one first substance, a corresponding adduct and the use of such an adduct for separating mixtures of substances.
