Abstract:
1. A coating material formulation comprising (A) 0.001%-45% by weight of a mixture comprising as component a1 at least one surfactant and as component a2 at least one compound corresponding to general formula (1) in which R R R n has an average value of 0 to 10, m has an average value of 1 to 10, where n+m≦10 and m>n, and the alkylene oxide structural units, which are optionally different, can be distributed randomly or arranged in blocks, wherein the ratio of component a1 to component a2 is 1:4 to 20:1, (B) 1%-95% by weight of film-forming binders and resins selected from the group consisting of nitrocellulose, alkyd resins, polyester resins, melamine-formaldehyde resins, acrylic resins, aqueous acrylate dispersions, polyurethane resins, polymers of vinyl chloride or vinyl ethers, epoxy acrylates, polyester acrylates, polyether acrylates, urethane acrylates, aldehyde resins, ketone resins, amino resins, carbamide resins, casein and mixtures thereof, (C) 0%-80% by weight of fillers, (D) 0%-40% by weight of pigments, (E) 0%-20% by weight of additives, and (F) 0%-90% by weight of organic solvents and/or water, the sum of the weight percentages of components (A) to (F) being 100% by weight, wherein the mixture (A) at a concentration of 0.2 g/l in water at 23° C. leads to a reduction in the contact angle on steel in comparison to pure water after 1 s by at least 15°, and the mixture in the CNOMO (prEN 14371:2004, 0.1 g/l, 25° C., measurement in water) possesses a foamability of less than 1200 ml during pumped circulation.
