Silicone surfactant for aqueous coatings, adhesives, printing inks and overprint varnishes with a considerable reduction in the surface tension and therefore an improvement in the substrate wetting. Does not increase the surface slip. Suitable for systems that do not contain co-solvents. The additive is especially recommended for all aqueous coatings, printing inks and overprint varnishes, particularly also for formulations which do not contain co-solvents.
