DOW DOWSIL ACP-3073 is a 100% active silicone defoamer with advanced thermo-mechanical traits. The gray-white viscous liquid (30,000-80,000 mPa·s) works stably at pH 14 and >100°C, cutting foam by 40% at 0.01%-0.1% dosage. ISO 9001/REACH-certified, it boosts fiber recovery by 18% in kraft/sulfite pulping and slashes water use by 25%.
Strong Process Adaptability: Performs steadily in pH 14 black liquor and high-temperature cooking.
100% Active Composition: No need for dilution due to full-active content.
Quick Defoaming: Nano-silicone particles break foam in 20 seconds (meets ASTM D892).
Cost-Saving: Lowers per-ton pulp treatment cost by 20% via optimized dosage.
Eco-Friendly: Free of APEO/VOC, complying with FDA 21 CFR 175.105.
Kraft Pulping: Prevents fiber loss during pH 12-14 black liquor cooking.
Paper Washing: Improves black liquor extraction in vacuum washers.
Effluent Treatment: Reduces sludge amount in high-COD wastewater (≥30,000 mg/L).
Industrial Cleaning: Works with pH 12-14 alkaline degreasers.
