TEGO Foamex N, a German silicone-hydrophobic nanocomposite, is an amber transparent liquid with 300-800 mPa·s viscosity. It stays active stably under ≤150°C and extreme shear (≥12,000 s⁻¹), suppressing 98% of foam at 0.02%-0.1% dosage. Certified by REACH, ISO 9001 and GB 30981-2020, it boosts gloss (≥95 GU) and chemical resistance in amine/amide-cured epoxy floors and UV screen inks.
Nano-Scale Defoaming: 0.2 μm silicone-hydrophobic particles clear bubbles in 2 seconds (per ASTM D892-XII).
Wide Compatibility: Stable in UV curing (≥250 mJ/cm²), 100% solid epoxy (amine value 300-500 mg KOH/g) and chlorinated rubber systems.
High-Temperature Stability: Viscosity change ≤1.8% at 150°C/30min baking.
Food-Safe: Complies with FDA 21CFR 175.300.
Cost-Effective: Concentrated formula cuts usage by 80% with 35% cost reduction.
Industrial Epoxy Floors: Reaches ≥6H hardness in amine-cured systems with ≥5mm thickness.
UV Screen Inks: Keeps dot gain ≤0.3% at printing speeds ≥50 m/min.
Marine Anticorrosion Paints: Endures ≥2,000h salt spray in chlorinated rubber coatings with ≥80% solid content.
Electronic Potting: Limits porosity to ≤0.005% in epoxy resins with ≥100,000 mPa·s viscosity.
