A defoamer that offers high performance without side effects

By Mary Page Bailey and Gerald Ondrey | October 1, 2020

When it comes to developing defoamers (photo) for paints and coatings, the general rule is that the stronger the defoaming strength, the higher the incompatibility. The Coatings and Additive business of this company has developed a novel defoamer, TEGO Foamex 852, that provides a combination of both effectiveness and compatibility. This new, patent-pending technology offers formulators a new level of freedom. The new defoamer was specifically developed for printing ink application, and can be used to successfully meet Swiss A, FDA and China GB guidelines. TEGO Foamex 852 is a siloxane-based defoamer for waterborne formulations, is 100 % active and thereby also solvent-free. Further product benefits include: excellent shear stability and long-term effectiveness, which is particularly relevant for long print runs or if the printing ink must be stored for long periods. — Evonik Industries AG, Essen, Germany
