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% active in most formulations.
Thermally stable up to 120°C, maintaining performance during high-temperature polymerization and processing.
Non-yellowing and non-staining—ideal for clear coatings, adhesives, and architectural paints.
Acrylic and styrene-acrylic emulsion polymerization reactors.
Architectural and industrial waterborne coatings (e.g., interior/exterior paints).
Adhesives and sealants manufacturing, especially PVA and SBR-based systems.
Textile sizing and finishing baths where foam interferes with uniform application.
Construction chemicals such as cementitious tile adhesives and grouts.
