DOW XIAMETER AFE-3018 Defoamer

DOW XIAMETER AFE-3018 is a 25% active silicone defoamer emulsion designed for harsh industrial settings. It is a milky homogeneous liquid (800-2,500 mPa·s viscosity), stays effective at pH 2-12 and ≤100°C, enabling fast foam collapse (over 48 hours of suppression) in coating resins and wastewater systems. ISO 9001 and REACH certified, it cuts polyether defoamer use by 45% via improved dispersion.

Product Information of DOW XIAMETER AFE-3018 Defoamer

  1. Ultra pH Adaptability: Works in pH 2-12 systems, including caustic wastewater treatment.

  2. Fast Defoaming: Nano silicone particles lower surface tension to 24.5 dyn/cm within 15 seconds.

  3. Heat Resistance: Remains stable in 100°C processes with no viscosity changes.

  4. Eco-Compliant: Contains no APEO and meets EU BPR/FDA regulations.

  5. Long-Lasting Suppression: Lowers foam regeneration rate to <5% in aeration tanks.

Areas of Application of DOW XIAMETER AFE-3018 Defoamer

  1. Water Treatment: Manages foam in cooling tower cycles (COD≥5,000 mg/L).

  2. Coatings Production: Eliminates fisheye flaws in latex paints (0.05-0.3% dosage).

  3. Paper Manufacturing: Controls foam in kraft pulping processes (pH 12-13).

  4. Chemical Cleaning: Boosts efficiency in alkaline degreasers (pH 14).

  5. Textile Dyeing: Reduces steam use in jet dyeing machines.
