Highly effective silicone-based defoamer for rapid foam knockdown in demanding aqueous systems.
Excellent compatibility with a broad range of waterborne coatings, adhesives, and industrial cleaners.
Low dosage requirement—typically effective at 0.05–0.3 wt% active addition level.
Stable under high-shear mixing and elevated temperatures up to 80 °C.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive formulations.
Waterborne architectural and industrial coatings (e.g., acrylic and PUD-based paints).
Aqueous adhesives and sealants, including pressure-sensitive and construction-grade formulations.
Industrial cleaning solutions, especially alkaline and low-foaming detergents.
Textile auxiliaries such as dyeing and finishing baths where foam control is critical.
Construction chemicals, including cementitious grouts and tile adhesives.
