Highly effective silicone-based defoamer for rapid foam knockdown and sustained foam control.
Excellent compatibility with water-based systems, including acrylic, vinyl acetate, and styrene-butadiene emulsions.
Low dosage requirement—effective at 0.05–0.3 wt% in most polymerization and coating formulations.
Thermally stable up to 120°C, supporting use in high-temperature reaction and processing conditions.
Non-yellowing and non-staining, preserving clarity and color fidelity in final products.
Emulsion polymerization (e.g., SBR, VAE, acrylic latices).
Architectural and industrial waterborne coatings.
Adhesives and sealants manufacturing.
Textile sizing and finishing formulations.
Construction chemicals, including cementitious and grout admixtures.
