Features Of BASF FoamStar SI 2213 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 — typically effective at 0.05–0.3 wt% active substance in final formulation.
Stable under high-shear mixing and elevated temperature conditions common in industrial coating and adhesive production.
Non-yellowing and does not impair gloss or film clarity in finished applications.
