DOWSIL FS 013A is a fluorosilicone defoamer with advanced thermo-mechanical properties to boost your competitiveness. It is a milky homogeneous liquid (2,500-3,500 mPa·s viscosity) that performs stably at pH 2-12 and ≤150°C, enabling rapid bubble collapse in high-shear processes. Certified by ISO 9001 and REACH, it cuts coating defects by 40% at 0.05%-0.5% dosage versus conventional defoamers while improving gloss (Ra ≤2 μm).
Fluorosilicone Performance Edge: Lowers surface tension by 50% compared to standard silicones (per ASTM D892).
Strong Process Compatibility: Works with 150°C/5 bar jet dryer systems.
Food-Grade Compliance: Meets FDA 21 CFR 176.170 standards for food-related applications.
Cost-Saving Advantage: Reduces cost per ton of coating by 15%, with 6-month dilution stability.
Eco-Friendly Safety: Free of APEO and conforms to GB 18582-2020 standards.
Paper Sizing: Boosts surface smoothness by 35% in starch sizing agents.
Textile Dyeing: Eliminates microbubbles in jet dyeing processes with ≥5 bar pressure.
Food Processing: Controls foam in pH 3-9 fermentation tanks.
Waterborne Coatings: Reduces roller marks in 5,000 rpm latex paint systems.
Petrochemicals: Cuts sludge volume in sulfur-removal wastewater (COD≥20,000 mg/L).
