DOW DOWSIL AFE-1267 Defoamer

DOW DOWSIL AFE-1267 is a high-solids silicone defoamer emulsion with advanced thermo-mechanical properties to boost your competitiveness. It is a milky homogeneous liquid (2,000 mPa·s viscosity) that performs stably at pH 1-14 and ≤150°C, achieving 40% foam reduction in metalworking fluids and mining effluent systems. Certified by ISO 9001 and REACH, it enhances process efficiency by cutting energy consumption by 25% at 0.3%-1.0% dosage.

Product Information of DOW DOWSIL AFE-1267 Defoamer

  1. Strong Process Compatibility: Maintains stability with pH 12 alkaline degreasers and high-temperature pulping processes.

  2. Fast Defoaming Action: Nano-silicone particles eliminate microbubbles within 20 seconds (compliant with ASTM D892).

  3. Concentrated Formula: 62% solid content allows 1:1 dilution for cost-effective application.

  4. Eco-Friendly Compliance: Free of APEO and VOC, meeting FDA 21 CFR 175.105 standards.

  5. Cost-Saving Performance: Lowers treatment cost per ton by 18%-20% through optimized dosage.

Areas of Application of DOW DOWSIL AFE-1267 Defoamer

  1. Metalworking Fluids: Controls foam in high-pressure jet systems with ≥50 bar pressure.

  2. Mining Effluent: Reduces sludge volume in high-COD wastewater (≥30,000 mg/L).

  3. Pulp Bleaching: Eliminates foam in ClO₂ bleaching processes (pH 3-5).

  4. Industrial Cleaners: Compatible with ultrasonic cleaning equipment (≥40 kHz).
