DOW XIAMETER AFE-3150 Defoamer

DOW XIAMETER AFE-3150 is a 55%-65% active silicone defoamer emulsion made for harsh industrial scenarios. It takes the form of a milky homogeneous liquid (800-3,000 mPa·s viscosity), stays effective at pH 3-12 and ≤120°C, and enables quick foam collapse (over 48 hours of suppression) in coating resins and paper pulping systems. ISO 9001 and REACH certified, it cuts mineral oil defoamer use by 60% via enhanced dispersion in high-shear processes.

Product Information of DOW XIAMETER AFE-3150 Defoamer

  1. Process Adaptability: Works in pH 3-12 systems, including caustic pulping baths.

  2. Heat Resistance: Endures 120°C conditions without viscosity changes.

  3. Nanoscale Performance: 5 μm particle size boosts penetration in nano-coatings.

  4. Eco-Friendliness: Contains no APEO and meets FDA 21 CFR 175.300 standards.

  5. Cost Efficiency: At 0.05%-0.3% dosage, its defoaming efficiency is 40% higher than polyether-based defoamers.

Areas of Application of DOW XIAMETER AFE-3150 Defoamer

  1. Coatings Production: Eliminates fisheye flaws in latex paints (0.05-0.2% dosage).

  2. Paper Pulping: Controls foam in kraft pulping processes (pH 12-13).

  3. Textile Dyeing: Lowers steam use in jet dyeing machines.

  4. Ink Manufacturing: Removes microbubbles during UV ink polymerization.

  5. Food Processing: Complies with GB 2760-2014 for application in fermentation processes.
