DOWSIL 1-6184 Defoamer

DOW DOWSIL 1-6184 is a premium 100% active fluorosilicone defoaming additive, based on fluoroalkyl-modified polysiloxane. It has 50% fluorine, stays stable at pH 2-12 and ≤150°C, with 300-1,000 cP viscosity and 1.15-1.17 g/cm³ density. It cuts surface tension below 21 dyn/cm, boosts oil-gas separation (40%+ foam reduction), offers lubricity/chemical inertness for high-salinity/high-shear use, and meets FDA 21 CFR 176.210 for food-grade apps.

Product Information of DOWSIL 1-6184  Defoamer

  1. High-Speed Defoaming: Nano fluorosilicone particles destroy micron foam in 5 minutes, perfect for high-pressure oil-gas systems.

  2. Extreme Condition Resistance: Endures pH 2-12 (strong acid/alkali), 150°C heat, and ≥5,000 rpm shear without performance drop.

  3. Extended Shelf Life: Remains stable for 360 days, no stratification at -20°C to 50°C after dilution.

  4. Eco-Friendly Compliance: APEO-free, VOC <50g/L, and certified under EU REACH and China GB 24408.

  5. Cost-Saving Performance: 0.05%-0.3% dosage lowers mineral oil defoamer consumption by 30%.

Areas of Application of DOWSIL 1-6184  Defoamer

  1. Oil-Gas Separation: Curbs foam in crude oil degassing (0.1%-0.5% dosage).

  2. Chemical Processing: Manages foam in kraft pulping to reduce equipment corrosion.

  3. Food Industry: FDA-compliant for foam control in fermenters and cleaning lines.

  4. Wastewater Treatment: Lessens foam in high-COD aeration tanks.
