Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage efficiency—typically effective at 0.05–0.3 wt% in final formulations.
Thermally stable up to 120 °C, maintaining performance during high-shear mixing and elevated-temperature processing.
Non-yellowing and non-staining, supporting clarity and color fidelity in sensitive coatings and adhesives.
Architectural and industrial waterborne coatings (e.g., interior/exterior paints and primers).
Water-based adhesives and construction sealants.
Textile and leather finishing auxiliaries.
Industrial cleaning formulations and metalworking fluids.
