DOWSIL FS 025 Defoamer

DOW DOWSIL FS 025 is a high-performance siloxane defoamer in transparent liquid form (300-500 mPa·s viscosity). It stays active at pH 2-12 and ≤150°C, collapses micron foam fast (dynamic surface tension ≤22 dyn/cm) with 6+ hours suppression, meets FDA 21 CFR 176.210 for food-grade inks. Blended with mineral oil defoamers, it cuts usage by 20% to boost coating and food processing efficiency.

Product Information of DOWSIL FS 025 Defoamer

  1. Fast Foam Collapse: Nano siloxane particles break foam in 3 minutes, suitable for high-shear coating dispersion processes.

  2. Extreme Condition Resistance: Withstands pH 2-12, high salinity, and 150°C heat without losing performance or degrading.

  3. Extended Shelf Life: Maintains stability for 360 days at -20°C to 50°C, staying homogeneous after dilution.

  4. Eco-Friendly Certification: APEO-free, VOC <50g/L, and compliant with EU REACH and China GB 24408 standards.

Areas of Application of DOWSIL FS 025 Defoamer

  1. Industrial Coatings: Removes roller marks in water/solvent coatings, increasing gloss by 15% when dosed at 0.1%-0.5%.

  2. Food Processing: FDA-compliant for foam control in fermenters and cleaning lines, with a maximum 0.3g/kg dosage per GB 2760-2014.

  3. Textile Dyeing: Manages foam in jet dyeing processes to lower the risk of fabric stains.
