The present invention relates to novel surfactant mixtures comprising at least one compound A whose dynamic surface tension γat a use concentration of 0.1% by weight and a bubble lifetime of 100 ms is <45 mN/m, and at least one compound B whose static surface tension ymeasured at a use concentration of 0.1% by weight is less than or equal to the static surface tension Yof compound A, to the use thereof as additives, for example in preparations for surface coating, such as paints, lacquers, protective coatings and special coatings in electronic or in optical applications. At least one compound in the novel surfactant mixture is a fluorosurfactant.
