DOW DOWSIL SR 2406 S is a high-performance silicone defoamer with advanced thermal-mechanical properties to boost your competitiveness. It is a transparent liquid (800-1,200 mPa·s viscosity) that performs stably at pH 3-12 and ≤120°C, enabling quick bubble collapse in coatings and adhesive systems. Certified by ISO 9001 and REACH, it cuts coating defects by 30% versus conventional defoamers while increasing gloss by 20%.
Wide Process Compatibility: Works with high-speed dispersers (5,000-10,000 rpm).
Nano-Grade Effectiveness: 8 μm silicone particles enhance coating leveling.
Chemical Stability: Does not react with epoxy or polyurethane curing systems.
Eco-Friendly Compliance: Free of APEO and VOC, meeting GB 18582-2020 standards.
Cost-Saving Performance: Delivers 15% cost savings when used at 0.05%-0.3% dosage.
Industrial Coatings: Eliminates microbubbles in water-based epoxy primers (0.1%-0.5% dosage).
Printing Inks: Controls foam in UV-curable inks (with 200-500 mPa·s viscosity).
Adhesive Production: Reduces porosity in polyurethane adhesives (during 80°C mixing).
Textile Finishing: Improves wash durability in coating processes (pH 8-10).
Paper Sizing: Suppresses foam in starch sizing agents (at 90°C).
