Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, 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 processing and storage.
Non-yellowing and non-staining, suitable for clear coatings and light-colored industrial finishes.
Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers).
Adhesives and sealants, particularly pressure-sensitive adhesives (PSAs) and latex-based bonding agents.
Textile and leather finishing formulations requiring foam control during padding and coating operations.
Construction chemicals, including cementitious mortars, tile adhesives, and grouts.
Water-based inks and overprint varnishes used in flexible packaging and label printing.
