DOWDOWSIL CE defoaming emulsion is a high-performance silicone-based defoamer with advanced thermal-mechanical properties to boost your competitiveness. It is a milky homogeneous liquid (800-3,000 mPa·s viscosity) that performs stably at pH 3-12 and ≤150°C, enabling rapid bubble collapse in waterborne coatings and industrial cleaning systems. Certified by ISO 9001 and REACH, it cuts coating defects by 40% at 0.01%-0.2% dosage versus conventional defoamers while increasing gloss by 18%.
Wide Process Compatibility: Stays stable in 150°C environments and pH 14 kraft pulping black liquor.
Nano-Grade Dispersion: Self-emulsifying silicone particles (D50≤5 μm) ensure uniform distribution.
Food-Grade Compliance: Meets FDA 21 CFR 176.170 standards for food-grade packaging uses.
Cost-Saving Performance: Lowers cost per ton of coating by 15% through optimized dosage.
Eco-Friendly Safety: Free of APEO and conforms to GB 18582-2020 standards.
Waterborne Coatings: Eliminates microbubbles in roller and spray processes (0.1%-0.5% dosage).
Paper Machine Operation: Controls foam in 1,800 m/min forming sections.
Industrial Cleaners: Works with pH 12 alkaline degreasers and ultrasonic systems.
Food Processing: Suppresses foam in pH 3-9 fermentation tanks.
Petrochemicals: Reduces sludge during high-COD wastewater (≥20,000 mg/L) treatment.
