DOW XIAMETER AFE-2310 is a 30% active silicone multiphase defoamer emulsion built for harsh industrial scenarios. It presents as a milky homogeneous liquid (800-3,000 mPa·s viscosity), stays effective at pH 2-12 and -20°C to 100°C, enabling fast foam collapse (over 48 hours of suppression) in coating polymerization and paper pulping systems. ISO 9001 and REACH certified, it cuts mineral oil defoamer use by 50% via enhanced dispersion in high-shear processes.
Thermal Versatility: Works in -20°C to 100°C environments, including cold-chain food processing.
Nanoscale Performance: 5 μm particle size boosts penetration in nano-coatings.
Ultra pH Adaptability: Functions effectively in pH 2-12 systems, such as caustic wastewater treatments.
Eco-Compliant: Contains no APEO and meets GB 9685-2016 standards.
Cost Efficiency: At 0.02%-0.5% dosage, its defoaming efficiency is 35% higher than polyether-based defoamers.
Paper Pulping: Controls foam in kraft pulping (pH 12-13) while improving drainage by 20%.
Industrial Coatings: Eliminates fisheye defects in latex paints under 5,000 rpm stirring.
Food Processing: Manages foam in fermentation tanks (compliant with FDA 21 CFR 175.300).
Textile Dyeing: Reduces steam consumption in jet dyeing machines.
Wastewater Treatment: Lowers sludge volume in high-COD effluent (≥8,000 mg/L).
