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, supporting high-temperature processing conditions.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive coatings and adhesives.
Architectural and industrial waterborne paints and coatings.
Textile and carpet printing pastes.
Adhesives and sealants, especially latex-based formulations.
Construction chemicals, including cementitious mortars and tile grouts.
Water treatment systems requiring controlled foam management during dosing and mixing.
