Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylic, styrene-acrylic, and vinyl acetate emulsions.
Low dosage efficiency—effective at 0.05–0.3% active on total formulation weight.
Thermally stable up to 120°C, maintaining performance during high-shear mixing and hot-process conditions.
Non-yellowing and non-staining, suitable for clear coatings and light-colored architectural finishes.
Architectural waterborne paints and interior/exterior wall coatings.
Industrial maintenance coatings, including primers and topcoats.
Adhesives and sealants based on latex or aqueous polymer dispersions.
Construction chemicals such as cementitious tile adhesives and grouts.
Textile printing pastes and pigment dispersion systems.
