Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate, and styrene-butadiene emulsions.
Low dosage requirement—typically effective at 0.05–0.3 wt% on total formulation.
Stable under high-shear mixing and elevated temperatures up to 90 °C.
Non-yellowing and does not impair film clarity or gloss in final coatings.
Architectural and industrial waterborne paints and coatings.
Adhesives and sealants, especially PVA and SBR-based formulations.
Textile printing pastes and pigment dispersions.
Construction chemicals, including cementitious tile adhesives and grouts.
Wood coatings and water-reducible varnishes.
