Essen, Germany. Evonik Coating Additives introduces TEGO® Foamex 8051, the latest addition to its TEGO® Foamex line of defoamers. This new, highly efficient siloxane defoamer is specifically designed for use in waterborne decorative coatings.

TEGO® Foamex 8051 offers coating formulators several advantages over other available defoamers. It provides a cost-effective solution for high-performance applications while meeting strict environmental regulations.

The additive is a 100% active defoamer concentrate based on polyethersiloxane technology, and it has been designed to be relatively easy to incorporate into formulations. It delivers consistent performance by effectively defoaming high PVC coatings, maintaining strong defoaming persistence under high shear, and working well in the grinding stage.

Additionally, it maintains its defoaming effectiveness even after storage. The product has broad global registrations (US, EU, China, Japan, etc.), contains no reportable hazardous substances, and complies with Ecolabel 2014/312/EU, with VOC levels at 0.08% and SVOC levels at 0.19% (DIN ISO 11890/2).

“With the launch of TEGO® Foamex 8051, we're offering a product that not only meets our -customers' demanding performance requirements but also supports our strategy to enable eco-friendly coatings,” says Katina Kiep, Head of Decorative Coatings at Evonik Coating Additives. “This innovative defoamer exemplifies our strategy of delivering customer-focused products that solve formulation challenges, turning them into outperformulations.”

Evonik's Coating Additives business offers a wide range of specialty additives for coatings and printing inks. With decades of experience, the business develops products for various coatings markets, including decorative coatings, industrial coatings, automotive coatings, and printing inks.
