Dowsil DK Q1-1074 Defoamer

DOWSIL DK Q1-1074 is a silicone defoamer for tough industrial use, made with polysiloxane and hydrophobic silica. It stays active at pH 2-12 and ≤150°C, has dynamic surface tension down to 25 mN/m, cuts foam defects by over 30% in coatings/inks, meets FDA 21 CFR 176.210 (fit for food-grade inks), and lowers mineral oil defoamer use by 20% when blended.

Product Information of Dowsil  DK Q1-1074 Defoamer

  1. Quick Foam Breakdown: Nano hydrophobic particles destroy micron foam in 5 minutes, perfect for high-shear coating/printing.

  2. Tough Environment Resistance: Withstands pH 2-12, high salinity, and 150°C heat without losing performance.

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

  4. Economical & Eco-Friendly: Requires only 0.05%-0.3% dosage, VOC <50g/L, and meets EU REACH and China GB 24408 standards.

Areas of Application of Dowsil  DK Q1-1074 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.
