DOW DOWSIL AFE-7600 is a concentrated silicone defoamer emulsion with advanced thermal-mechanical properties to boost your competitiveness. It is a milky homogeneous liquid (70,000 mPa·s viscosity) that performs stably at pH 1-14 and ≤150°C, achieving 40% foam reduction at 0.1%-0.5% dosage. Certified by ISO 9001 and REACH, it improves fiber retention by 15% in kraft pulping black liquor processes while optimizing cleaning efficiency.
Wide Process Tolerance: Maintains stability in pH 14 environments and 150°C kraft pulping stages.
Concentrated Cost-Efficiency: Contains 54-58% active content and 60-69% solids for economical dilution.
Fast Defoaming Action: Nano-silicone particles collapse bubbles within 20 seconds (per ASTM D892).
Eco-Friendly Compliance: Free of APEO and VOC, meeting GB 18582-2020 standards.
Strong Shear Resistance: Works with ≥50 bar jet cleaning and 1,800 m/min paper machines.
Pulp Cooking: Lowers fiber loss in pH 12-14 black liquor digestion processes.
Metal Cleaning: Eliminates microbubbles in pH 12 alkaline degreasers.
Liquid Detergents: 0.25% dosage ensures foam control even after 12 weeks of aging at 40°C.
Effluent Treatment: Reduces sludge by 50% in high-COD wastewater.
Paper Machine: Enhances sheet uniformity in 1,800 m/min forming sections.
