Organosilicon defoamers are composed of modified polysiloxanes compounded with hydrophobic particles (such as silica), featuring extremely low surface tension. They can rapidly penetrate into the foam film, achieving quick defoaming and long-lasting suppression by disrupting the surface balance of the liquid film. Thanks to their chemical inertness, non-toxicity, and low dosage requirements, they are widely used in industrial wastewater treatment, fermentation processes, papermaking, and coatings production, serving as a key additive to ensure production efficiency and product quality.
