DOW DOWSIL Antifoam 2410 Defoamer

DOW DOWSIL Antifoam 2410 is a polysiloxane-based defoamer with advanced thermal-mechanical properties to boost your competitiveness. It is a milky homogeneous liquid (1,000-3,000 mPa·s viscosity) that performs stably at pH 3-12 and ≤150°C, achieving rapid bubble collapse via "bridging-dewetting" mechanisms. Certified by ISO 9001 and REACH, it cuts coating defects by 30% at 0.05%-0.5% dosage versus mineral oil-based alternatives, while improving process efficiency in tough industrial uses.

Product Information of DOW DOWSIL Antifoam 2410 Defoamer

  1. Strong Process Stability: Maintains performance in 150°C environments and pH 14 kraft pulping processes.

  2. Nano-Grade Dispersion: Self-emulsifying silicone particles (D50≤5 μm) ensure uniform distribution.

  3. Fast Defoaming Action: Eliminates microbubbles within 20 seconds (compliant with ASTM D892).

  4. Chemical Inertness: Works well with epoxy and polyurethane curing systems.

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

Areas of Application of DOW DOWSIL Antifoam 2410 Defoamer

  1. Industrial Coatings: Controls microbubbles in waterborne epoxy primers (0.1%-0.5% dosage).

  2. Pulp Processing: Reduces fiber loss during 160-170°C black liquor treatment.

  3. Textile Dyeing: Improves color fastness in jet dyeing systems with ≥5 bar pressure.

  4. Food Fermentation: Suppresses foam in pH 3-9 fermentation tanks (compliant with HACCP).

  5. Petrochemicals: Lowers sludge volume in high-COD wastewater (≥20,000 mg/L) treatment.
