DOW DOWSIL ACP-3258 is a 100% active silicone defoamer compound with advanced thermo-mechanical properties to boost your competitiveness. It is a gray-yellow viscous liquid (20,000-40,000 mPa·s viscosity) that performs stably at pH 14 and >100°C, achieving 40% foam reduction at 0.01%-0.1% dosage. Certified by ISO 9001 and REACH, it improves fiber recovery by 18% in kraft and sulfite pulping processes while cutting water consumption by 25%.
Wide Process Tolerance: Maintains stability in pH 14 black liquor and high-temperature cooking stages.
100% Active Formula: Full-active content eliminates the need for dilution.
Fast Defoaming Action: Nano-silicone particles collapse foam within 20 seconds (compliant with ASTM D892).
Cost-Saving Performance: Lowers treatment cost per ton of pulp by 20% through optimized dosage.
Eco-Friendly Compliance: Free of APEO and VOC, meeting FDA 21 CFR 175.105 standards.
Chemical Pulping: Controls fiber loss in pH 12-14 kraft cooking processes.
Paper Washing: Enhances black liquor extraction efficiency in vacuum washers.
Effluent Treatment: Reduces sludge volume in high-COD wastewater (≥30,000 mg/L).
Industrial Cleaning: Compatible with pH 12-14 alkaline degreasers.
