Highly effective silicone-based defoaming agent with rapid knock-down and lasting 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% in formulation, minimizing impact on final product properties.
Thermally stable up to 120°C, maintaining performance during high-shear mixing and elevated-temperature processing.
Non-yellowing and non-staining, suitable for clear coatings, adhesives, and white pigmented systems.
Architectural and industrial waterborne paints and coatings.
Emulsion polymerization processes (e.g., SBR, VAE, and acrylic lattices).
Water-based adhesives and sealants.
Textile printing pastes and pigment dispersions.
Construction chemicals, including cementitious grouts and tile adhesives.
