TEGO® Antifoam 2290 by Evonik is a self-emulsifying, APEO-free organic antifoam concentrate. It is free of silicone and does not contain any silica. It is used in formulation and application of polymer dispersions/latices such as adhesives based on acrylates or PVAc. High shear forces on the diluted product should be avoided.

• It process aid for water-based polymerization of dispersions, thermoplastics and elastomers (e.g. de-monomerisation of SBR or NBR emulsions, handling of acrylates).
• Recommended dosage may vary from 0.005-0.2%.
• TEGO® Antifoam 2290 has a shelf life of 12 months.

TEGOPREN® 5890 by Evonik is an organo-modified siloxane. It is a solvent-free, easy to handle liquid, acts as an anti-foaming and wetting agent. It is highly efficient in fighting dry foam and shows an outstanding dispersibility and dilution stability. It improves the dewatering of S-PVC after stripping. It is recommended for the production of transfer labels and tapes or for laminating processes as well as for the production of dispersions like reaction, blow down and stripping.

• It is compatible with cellulose, polyvinyl alcohols, PVC suspension, ethylene vinyl acetate copolymers (EVAc) and polyvinyl acetate (PVAc).
• TEGOPREN® 5890 is used in water-based polymerization processes and adhesives.
• The recommended dosage may vary between 0.01 to 1.0%.
• It has a shelf life of 12 months.
