Dowsil ACP-3379 Defoamer

DOWSIL ACP-3379 is a 100% active silicone defoamer concentrate engineered for harsh industrial environments. It uses polysiloxane-polyether composite technology to enable rapid bubble collapse (dynamic surface tension ≤25 mN/m) and long-term foam suppression (24+ hours). With self-emulsifying properties, it delivers efficacy at ultra-low dosages (1–5 ppm), boosting kraft/sulfite pulping efficiency (20% energy reduction) while complying with FDA 21 CFR 176.170/180/210 for food-grade pulp. Stable across pH 2–12 and temperatures ≤80°C, it reduces mineral oil defoamer usage by 30% when blended.

Product Information of Dowsil  ACP-3379 Defoamer

  1. Ultra-Low Dosage Efficiency: 1–5 ppm dosage replaces traditional defoamers, cutting costs by 40%.

  2. Harsh Condition Tolerance: Resists strong acid/alkali (pH 2–12), high salinity, and heat up to ≤80°C.

  3. Self-Emulsifying: Nano-dispersible for direct dosing or dilution, no equipment modification required.

  4. Eco-Compliance: APEO-free, VOC<50g/L; certified under EU REACH and China GB 24408.

  5. Long Shelf Life: 720-day stability without stratification when stored at 4–50°C.

Areas of Application of Dowsil  ACP-3379 Defoamer

  1. Chemical Pulping: Suppresses black liquor foam in kraft pulping (0.05%–0.2% dosage).

  2. Paper Bleaching: Controls foam in H₂O₂ bleaching to ensure uniform whiteness.

  3. Food Processing Wastewater: Manages foam in fermenters/wash lines, meeting indirect food contact standards.

  4. Industrial Wastewater: Reduces foam in high-COD aeration tanks, minimizing sludge carryover.
