New EcoLabel-Certified Multi-Purpose Bio-Based Defoamer for Architectural Paints

"Bio-based" characteristics are not the only requirement for a good defoamer. In fact, there are many demands placed on good defoamers for the architectural sector; the additive must be well-tolerated, meet EcoLabel standards, be applicable as broadly as possible, and of course reliably prevent foam formation. Evonik's new defoamer TEGO® Foamex 18 meets these requirements.

TEGO® Foamex 18 enriches the Coating Additives business unit's already comprehensive defoamer portfolio and adds a unique property profile; the new defoamer consists of 98% vegetable oil, a renewable raw material. TEGO® Foamex 18 is Evonik's first bio-based defoamer developed specifically for the architectural market. Nadia Lenhardt, Head of EMEA, Decorative Coatings Market Segment, says: "The trend toward sustainable formulations in the market is continuous. Our additives for water-based formulations have been used for decades. The new bio-based additive is a consistent next step in our efforts to provide sustainable formulations for bio-based paints."

TEGO® Foamex 18 exhibits an excellent balance between effectiveness and compatibility. It is also easy to process and suitable for both grinding and discharge stages. As a result, the defoamer is universally applicable and therefore equally suitable for a wide range of formulations. The additive also meets all relevant EcoLabel requirements, such as Blue Angel and EU Ecolabel.

By continuously expanding its existing defoamer portfolio not only for the architectural sector but also for industrial, automotive and printing ink applications, Evonik Coating Additives offers the best possible solution for virtually all desired formulations.
