Highly effective silicone-based defoamer for rapid foam knock-down 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 on total formulation.
Thermally stable up to 120 °C, maintaining performance during high-temperature polymerization and processing.
Non-silicone residue, minimizing surface defects and ensuring good intercoat adhesion in coatings and adhesives.
Latex paint and architectural coatings manufacturing.
Adhesive and sealant formulations, especially pressure-sensitive and water-based types.
Textile sizing and finishing baths where foam interferes with uniform application.
Construction chemicals, including cementitious tile adhesives and grouts.
Industrial cleaning concentrates and aqueous process fluids.
