DOWSIL 62 Additive is a water-based silicone defoamer engineered for inks and coatings, leveraging polyether modification technology for efficient foam control and long-term stability. With 57% active content, it rapidly eliminates micron-sized bubbles across pH 2–12, reduces dynamic surface tension to 25.2 dyn/cm, and boosts leveling and gloss by +15%. It maintains performance under high temperatures (≤150°C) and shear, minimizing pinholes and craters. FDA-compliant (21 CFR 175.105/176.210), it suits eco-sensitive uses like food packaging inks, while meeting strict standards (APEO-free, VOC<50g/L, REACH/China GB 24408 compliant).
High-Efficiency Defoaming: 2000 mPa·s viscosity optimizes bubble rupture in high-solids systems (e.g., printing pastes).
Strong Compatibility: Works with acrylic/PU resins without impacting recoatability.
Eco-Safety: APEO-free, VOC<50g/L; compliant with REACH and China GB 24408.
Long Shelf Life: 540-day stability when stored at 4–50°C.
Cost-Effective: Effective at 0.05%–0.5% dosage, lowering operational costs.
Printing Inks: Reduces streaks in flexo/gravure inks and speeds up drying.
Industrial Coatings: Enhances scratch resistance in coil/auto OEM paints.
Wood Coatings: Improves clarity in waterborne UV primers.
Food Packaging: FDA-compliant for safe ink formulations.
