DOWSIL FS OC-2 Defoamer

DOW DOWSIL FS Antifoam OC-2 is a 100% active silicone defoamer made for extreme industrial conditions. Its organically modified siloxane formula stays stable at ≤150°C and high shear, has dynamic surface tension as low as 24 dyn/cm, quickly collapses micron foam (8+ hours suppression), works with aqueous/non-aqueous systems, excels in solvent-free adhesives and UV-cured resins, and boosts chemical and food processing efficiency.

Product Information of DOWSIL FS OC-2 Defoamer

  1. Fast Foam Elimination: Nano silicone particles remove foam in 5 minutes, perfect for high-pressure spraying scenarios.

  2. Extreme Condition Resistance: Endures 150°C heat, ≥5,000 rpm shear, and pH 2-12 environments without performance degradation.

  3. Wide Compatibility: Great affinity with organic materials, reducing coating defects in UV-sensitive systems.

  4. Eco & Cost-Efficient: Zero VOC, meets FDA 21 CFR 175.300, and 0.05%-0.3% dosage cuts costs by 40%.

  5. Convenient Handling: Supports direct dosing (no pre-emulsification) and comes in 18kg snap-lid drum packaging.

Areas of Application of DOWSIL FS OC-2 Defoamer

  1. Chemical Processing: Manages foam in solvent-free adhesives, with a dosage of 0.1%-0.5%.

  2. Food Packaging: FDA-compliant for inks and coatings, with a maximum dosage of 0.3g/kg.

  3. UV-Cured Materials: Curbs bubbles in resin systems to ensure uniform curing.

  4. Industrial Lubricants: Defoams non-aqueous oils to prolong equipment service life.
