Features Of Evonik TEGOPREN 5885 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylic, styrene-acrylic, and vinyl acetate copolymer dispersions.
Low dosage requirement—effective at 0.05–0.3 wt% in final formulation—minimizing impact on product properties.
Good storage stability and thermal resistance up to 60 °C without phase separation or viscosity change.
Non-yellowing and non-silicone-residue-forming, supporting clear coatings and high-gloss applications.
