Name: Wacker SILFOAM SE 47 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Wacker SILFOAM SE 47 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage requirement—typically effective at 0.05–0.3 wt% in final formulation—minimizing impact on product properties.
Stable under high-shear mixing and elevated temperatures up to 90 °C during polymerization and processing.
Non-yellowing and odor-neutral, supporting use in sensitive applications such as architectural coatings and adhesives.

Typical Applications Of Wacker SILFOAM SE 47 Defoamer

Acrylic and vinyl acetate-based emulsion polymers (e.g., binders for paints and coatings).
Styrene-butadiene rubber (SBR) latex production and modification.
Waterborne adhesives and sealants manufacturing.
Architectural and industrial coating formulations, especially during pigment grinding and let-down stages.
Textile sizing and finishing baths where persistent foam interferes with uniform application.
