DOW DOWSIL FS 92, a high-performance siloxane defoamer, is crafted for harsh industrial settings. It contains hydrophobic silica-enhanced polysiloxane, ensuring stable operation across pH 2 - 12 and at temperatures up to 150°C. With a dynamic surface tension as low as 22 dyn/cm, it swiftly breaks down micron-level foam, providing over 6 hours of suppression. Being FDA 21 CFR 176.210 compliant, it's suitable for food-grade applications. When blended with mineral oil defoamers, it cuts their usage by 20%, thus enhancing efficiency in food processing and oilfield operations.
Swift Defoaming Action: Its nano siloxane particles are engineered to burst foam within just 3 minutes. This makes it an ideal choice for high-shear environments such as filling lines in food processing and oil separation processes in the oilfield.
Exceptional Condition Tolerance: DOW DOWSIL FS 92 can resist extreme conditions. It stands up to the wide pH range of 2 - 12, high salinity levels, and temperatures as high as 150°C without any degradation in performance.
Extended Shelf Life: Maintaining product quality over time is crucial. This defoamer offers a 360-day stability period. Even after dilution, it remains homogeneous across a temperature range of -20°C to 50°C.
Eco-Friendly Compliance: In an era of environmental consciousness, this product shines. It is APEO-free, has a VOC content of less than 50g/L, and holds certifications under both EU REACH and China GB 24408, ensuring it meets strict environmental standards.
Food Processing: Given its FDA compliance, it's perfect for controlling foam in fermenters and cleaning lines in food processing facilities. The maximum allowable dosage, as per GB 2760 - 2014, is 0.3g/kg.
Oilfield Operations: In the oilfield, it suppresses foam during crude oil degassing. By doing so, it improves the separation efficiency, especially when dosed at 0.1% - 0.5%.
Cosmetics Manufacturing: During the emulsion polymerization process in cosmetics production, DOW DOWSIL FS 92 controls foam. This ensures that the final products have a uniform texture.
