Name: BASF FoamStar SI 2210 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of BASF FoamStar SI 2210 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% on total formulation—minimizing impact on final product properties.
Stable under high-shear mixing and elevated temperatures up to 80 °C during production and storage.
Non-yellowing and non-staining, preserving clarity and color stability in sensitive coatings and adhesives.

Typical Applications Of BASF FoamStar SI 2210 Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers, and clear coats).
Water-based adhesives and sealants, including PVA, EVA, and acrylic emulsion formulations.
Construction chemicals such as cementitious tile adhesives, grouts, and self-leveling compounds.
Industrial cleaning agents and aqueous metalworking fluids requiring persistent foam control.
