DOWSIL FS EPL Defoamer

DOW DOWSIL FS Antifoam EPL is a 28% active siloxane defoamer built for demanding industrial processes like emulsion polymerization and latex production. Its nonionic property (pH 7.8) stays stable under high shear and pumping, with 1,400 mPa·s viscosity and 29.6 dyn/cm surface tension to quickly eliminate micron foam (6+ hours suppression). Fully compatible with anionic/cationic surfactants, it cuts mineral oil defoamer use by 30% while boosting production efficiency.

Product Information of DOWSIL FS EPL Defoamer

  1. Shear Resistance: 1,400 mPa·s viscosity guarantees stability during pumping and high-speed mixing processes.

  2. Broad Compatibility: Nonionic nature allows use in anionic/cationic systems without forming complexes.

  3. Long Shelf Life: Maintains 360-day stability with no stratification at -20°C to 50°C—even at 1:10 dilution.

  4. Cost Efficiency: 28% active content lowers dosage to 0.05%-0.5%, reducing costs by 20%.

  5. Eco-Safe: APEO-free, VOC <50g/L, and compliant with EU REACH and China GB 24408 standards.

Areas of Application of DOWSIL FS EPL Defoamer

  1. Emulsion Polymerization: Controls foam in acrylic/VAE emulsion reactors, with a dosage of 0.1%-0.3%.

  2. Latex Products: Eliminates pinholes in production lines for medical gloves and condoms.

  3. Industrial Detergents: Suppresses foam in high-surfactant systems to enable efficient filling.

  4. Pulp Processing: Enhances dewatering efficiency and reduces sludge carryover during production.
