<p>The invention relates to a coating agent formulation containing a mixture that is composed of at least one surfactant as component a1 and at least one compound that corresponds to general formula (I) R1-O-(CH2-CHR2-O)n-(CH2-CH2-O)m-R3 as component a2. In said formula: R1 represents an optionally substituted phenyl or C4-C14 alkyl; R2 represents C1-C8 alkyl; R3 represents hydrogen, C1-C6 alkyl, benzoyl, acetyl, acryl or methacryl; n represents an average value from 0 to 10; and m represents an average value from 1 to 10, whereby n+m = 10 and m > n. According to the invention, the optionally different alkylene oxide structural units can be statistically distributed or arranged in blocks. The mixture also contains 1-95 wt. % coating forming binding agents and resins, 0-80 wt. % fillers, 0-40 wt. % pigments, 0-20 wt. % additives and 0-90 wt. % organic solvents and/or water, the sum of the weight percentages totalling 100 wt. %. The invention also relates to the use of the inventive mixtur e for lowering the interfacial tension in a coating agent, by the addition of said mixture to the latter.</p> |
