Dowsil AFE-3101 Defoamer

DOWSIL AFE-3101 is a 20% active silicone defoamer emulsion, crafted for industrial water systems and chemical processing. Using nonionic emulsification, it enables fast bubble collapse (dynamic surface tension ≤25 mN/m) and 8+-hour long suppression. The off-white emulsion (700 cSt viscosity) stays stable at pH 3.5-5 and high temps (flash point >100°C), boosting efficiency in agrochemicals and liquid detergents. It meets FDA 21 CFR 176.210, has good dilution stability, and cuts costs by 30% at 10-500 ppm dosages.

Product Information of Dowsil  AFE-3101 Defoamer

  1. Tough Environment Resistance: Endures pH 3.5-5, high salinity, and 80°C heat.

  2. Eco-Friendly Compliance: Free of APEO, VOC<50g/L, and certified by EU REACH and China GB 24408.

  3. Cost-Saving Use: 1:3-1:5 pre-dilution reduces consumption by 40% compared to traditional defoamers.

  4. Extended Shelf Life: Keeps stable for 360 days without stratification at 4-50°C.

Areas of Application of Dowsil  AFE-3101 Defoamer

  1. Agrochemicals: Curbs foam in pesticide formulations to ensure uniform spraying (0.2%-3% dosage).

  2. Industrial Water: Manages foam in high-COD aeration tanks, lowering sludge carryover.

  3. Liquid Detergents: Reduces foam residue in cleaners, enhancing rinse efficiency.

  4. Chemical Processing: Guarantees continuous production in reactors and filling lines.
