TEGO Foamex 860 is a German-origin defoamer, formulated as a polyether-modified silicone nanocomposite. Engineered with advanced thermo-mechanical properties to secure a competitive edge, it appears as a slightly hazy liquid with a viscosity of 80-250 mPa·s. It maintains stable activity under pH 3-12 and temperatures ≤95°C, achieving 96% foam suppression at a dosage of 0.05%-0.2%. Certified by REACH, ISO 9001, and GB 30981-2020, it enhances leveling (Ra≤0.12 μm) and drying efficiency in water-based industrial coatings and gravure ink systems.
Universal Compatibility: Stable in waterborne acrylics (Tg 20-80°C), PU dispersions (≤100 nm), and epoxy emulsions, adapting to a wide range of water-based formulations.
Nano Response: Features 0.35 μm modified silicone particles that eliminate bubbles in 5 seconds (per ASTM D892-VII standards), ensuring efficient foam control.
Long-Term Stability: Prevents foam regeneration for 28 days at 50°C/80% relative humidity, maintaining consistent performance over extended periods.
Zero VOC Certification: Compliant with HJ 2537-2014 (VOC ≤1 g/L), meeting strict environmental and regulatory standards for low volatile organic compound emissions.
Heavy-Duty Waterborne Paints: Achieves a DOI (Distinctness of Image) ≥94 in spray systems with ≥50% solids, enhancing the finish quality of durable waterborne paints.
Flexo Packaging Inks: Controls color density variation (ΔE≤0.2) on NY/CPP (nylon/cast polypropylene) substrates at speeds ≥600 m/min, ensuring consistent print quality in high-speed flexography.
Paper Cup Coatings: Limits oxygen transmission to ≤5 cc/m²/day in PE emulsions with ≥8 MFI (Melt Flow Index), preserving the barrier properties of paper cup coatings.
