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—effective at 0.05–0.3 wt% in most formulations—minimizing impact on final product properties.
Thermally stable up to 120 °C, supporting high-temperature processing conditions.
Non-yellowing and non-staining, suitable for clear coatings and light-colored applications.
Architectural and industrial waterborne paints and coatings.
Adhesives and sealants, especially latex-based formulations.
Construction chemicals including cementitious mortars and tile adhesives.
Textile auxiliaries such as dyeing and finishing baths.
Water treatment systems requiring foam control in biological and clarification processes.
