Highly effective silicone-based defoamer with rapid knock-down and long-term foam suppression.
Excellent compatibility with water-based emulsions, including acrylic, styrene-butadiene, and vinyl acetate systems.
Low dosage requirement — typically effective at 0.05–0.3% w/w in final formulation.
Thermally stable up to 120°C, maintaining performance during high-shear mixing and elevated processing temperatures.
Non-yellowing and non-staining, ensuring no impact on product color or clarity in sensitive applications.
Architectural and industrial waterborne paints and coatings.
Adhesives and sealants based on synthetic latex emulsions.
Textile sizing and finishing formulations.
Construction chemicals, including cementitious tile adhesives and grouts.
Water-based inks and pigment dispersions.
