DOWSIL FS 1224 Defoamer

DOW DOWSIL FS 1224 is a high-performance siloxane defoamer for tough industrial scenarios, formulated with polysiloxane enhanced by hydrophobic silica. It stays active at pH 2-12 and ≤150°C, has dynamic surface tension as low as 22 dyn/cm, collapses micron foam quickly (6+ hours suppression), and meets FDA 21 CFR 176.210 for food-grade uses. Blended with mineral oil defoamers, it cuts usage by 20% to boost chemical and food processing efficiency.

Product Information of DOWSIL FS 1224 Defoamer

  1. Fast Foam Breakdown: Nano siloxane particles destroy foam in 3 minutes, perfect for high-shear coating dispersion.

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

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

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

  5. Cost-Saving Performance: 0.1%-1% dosage reduces costs by 30% compared to traditional defoamers.

Areas of Application of DOWSIL FS 1224 Defoamer

  1. Chemical Processing: Curbs foam in acid/alkali reactions to lower equipment corrosion (0.1%-0.5% dosage).

  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. Wastewater Treatment: Lessens foam in high-COD aeration tanks for smoother operation.

  4. Textile Dyeing: Manages foam in jet dyeing processes to minimize fabric stains.
