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% on total formulation—minimizing impact on final product properties.
Thermally stable up to 120 °C, supporting high-temperature polymerization and processing conditions.
Non-yellowing and non-staining, preserving clarity and color stability in sensitive coatings and adhesives.
Acrylic and styrene-acrylic emulsion polymerization (e.g., paints, architectural coatings).
Vinyl acetate-ethylene (VAE) copolymer production for adhesives and construction binders.
Textile sizing and finishing formulations where foam control is critical during padding and coating.
Water-based inks and overprint varnishes requiring low-foam rheology and surface defect control.
Industrial cleaning concentrates and detergents with high-surfactant loadings.
