BYK-348

Silicone surfactant for aqueous coatings, adhesives, printing inks and overprint varnishes with a considerable reduction in the surface tension. Suitable for systems that do not contain co-solvents. The additive produces a significant decrease in the surface tension of aqueous systems and therefore particularly improves substrate wetting and leveling. It only marginally, if at all, stabilises foam and the recoatability is not impaired. The additive does not increase the surface slip. If a greater surface slip is required, we recommend that it is combined with a polysiloxane such as BYK-333. The additive is especially recommended for all aqueous coatings, printing inks and overprint varnishes, particularly also for formulations which do not contain co-solvents.
