Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylic, vinyl acetate, and styrene-butadiene emulsions.
Low dosage requirement—typically effective at 0.05–0.3 wt% active in final formulation.
Thermally stable up to 120°C, maintaining performance during high-temperature polymerization and processing.
Non-yellowing and non-staining, supporting clarity and color fidelity in sensitive coatings and adhesives.
Acrylic and styrene-acrylic emulsion paints and architectural coatings.
Waterborne adhesives and construction sealants.
Textile printing pastes and pigment dispersions.
Industrial cleaning formulations and metalworking fluids.
Latex-based caulks and elastomeric roof coatings.
