Dowsil DK Q1-1076 Defoamer

DOWSIL DK Q1-1076 is a 30% active polyether-modified silicone defoamer for tough industrial uses. With 500-1,500 mPa·s viscosity, it stays active at pH 2-12 and ≤80°C, drops dynamic surface tension to 24 mN/m, cuts coating/ink foam defects by 25%+, meets FDA 21 CFR 175.300 (fit for food-grade inks), and lowers mineral oil defoamer use by 20% when blended.

Product Information of Dowsil  DK Q1-1076 Defoamer

  1. Quick Foam Breakdown: Nano hydrophobic particles destroy micron foam in 3 minutes, perfect for high-shear coating/printing.

  2. Tough Environment Resistance: Withstands pH 2-12, high salinity, and 80°C heat without performance drop.

  3. Extended Shelf Life: Stays stable for 360 days, no stratification at 4-50°C after dilution.

  4. Economical & Eco-Friendly: Uses 0.1%-1% dosage, VOC <50g/L, and meets EU REACH and China GB 24408.

  5. Simple Integration: Liquid premix works with existing dosing systems.

Areas of Application of Dowsil  DK Q1-1076 Defoamer

  1. Industrial Coatings: Gets rid of roller marks in water/solvent coatings, boosting gloss by 15% at 0.1%-0.5% dosage.

  2. Food Packaging Inks: FDA-compliant, ensuring bubble-free and clear printing.

  3. Petrochemicals: Manages foam during crude oil separation and wastewater treatment.

  4. Detergent Production: Lessens foam in high-surfactant systems to enable efficient filling.
