DOW DOWSIL ACP-3073 Defoamer

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%.

Product Information of DOW DOWSIL ACP-3073 Defoamer

  1. Strong Process Adaptability: Performs steadily in pH 14 black liquor and high-temperature cooking.

  2. 100% Active Composition: No need for dilution due to full-active content.

  3. Quick Defoaming: Nano-silicone particles break foam in 20 seconds (meets ASTM D892).

  4. Cost-Saving: Lowers per-ton pulp treatment cost by 20% via optimized dosage.

  5. Eco-Friendly: Free of APEO/VOC, complying with FDA 21 CFR 175.105.

Areas of Application of DOW DOWSIL ACP-3073 Defoamer

  1. Kraft Pulping: Prevents fiber loss during pH 12-14 black liquor cooking.

  2. Paper Washing: Improves black liquor extraction in vacuum washers.

  3. Effluent Treatment: Reduces sludge amount in high-COD wastewater (≥30,000 mg/L).

  4. Industrial Cleaning: Works with pH 12-14 alkaline degreasers.
