DOW XIAMETER AFE-3168 Defoamer

DOW XIAMETER AFE-3168 is a 30% active silicone defoamer emulsion made for tough textile industrial settings. It is a beige liquid (2,500 mPa·s viscosity), stays effective at pH 2-12 and ≤100°C, enabling fast foam collapse (over 48 hours of suppression) in dyeing jets and wastewater systems. ISO 9001 and REACH certified, it cuts polyether defoamer use by 40% in reactive dye printing via improved dispersion.

Product Information of DOW XIAMETER AFE-3168 Defoamer

  1. Ultra pH Adaptability: Works in pH 2-12 systems, including caustic desizing baths.

  2. Heat Resistance: Remains stable in 100°C dyeing processes with no precipitation.

  3. Fast Defoaming: Nano silicone particles lower surface tension to 32.9 dyn/cm in 10 seconds.

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

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

Areas of Application of DOW XIAMETER AFE-3168 Defoamer

  1. Textile Dyeing: Controls foam in reactive dye jet processes (0.05-0.2 g/L dosage).

  2. Desizing & Bleaching: Manages foam in NaOH-based systems (pH 13).

  3. Wastewater Treatment: Reduces sludge volume in high-COD effluent (≥5,000 mg/L).

  4. Industrial Cleaning: Suppresses foam in alkaline degreasers (pH 14).

  5. Chemical Blending: Works well with dispersants and leveling agents.
