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—typically effective at 0.05–0.3 wt% active in final formulation.
Thermally stable up to 120 °C, maintaining performance during high-temperature processing and storage.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive coatings and adhesives.
Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers).
Adhesives and sealants, particularly pressure-sensitive adhesives (PSAs) and construction mastics.
Textile and leather finishing formulations requiring low-foam processing.
Construction chemicals, including cementitious tile adhesives and self-leveling underlayments.
Water-based inks and overprint varnishes for flexographic and gravure printing.
