  • Surfactant mixtures
    Patent number: 10590262
    Abstract: The present invention relates to novel surfactant mixtures comprising at least one compound A whose dynamic surface tension ?dyn. at 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 ystat measured at a use concentration of 0.1% by weight is less than or equal to the static surface tension Ystat of 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.
