TEGO Airex 900 is a German-origin defoamer, formulated as a silicone-nonionic surfactant nanocomposite. Engineered with advanced thermo-mechanical properties to secure a competitive edge, it appears as a clear to slightly hazy liquid with a viscosity of 50-150 mPa·s. It maintains stable activity under temperatures ≤120°C and extreme shear (≥10⁴ s⁻¹), achieving 95% foam suppression at a dosage of 0.03%-0.08%. Certified by REACH, ISO 9001, and GB/T 23986-2009, it enhances leveling (Ra≤0.1 μm) and curing efficiency in radiation-curing systems and two-component epoxy formulations.
Universal Compatibility: Stable in UV/EB curing systems (≥200 mJ/cm²), 100% solid epoxy (with amine value 200-400 mg KOH/g), and solvent-borne acrylics (≥60% solids), adapting to diverse formulation types.
Nano Enhancement: Features 0.25 μm silicone particles that collapse bubbles in 2 seconds (per ASTM D892-VIII standards), ensuring rapid and effective foam control.
High-Temp Resistance: Exhibits ≤2% viscosity change when baked at 120°C, maintaining stability in high-temperature processing.
Epoxy Self-Leveling Floors: Achieves ≥5H hardness in ≥3mm amine-cured epoxy systems, enhancing the durability and strength of self-leveling floor coatings.
UV Screen Inks: Controls dot gain to ≤0.5% at curing speeds ≥30 m/min, ensuring precise and consistent print quality in UV screen printing.
Wood UV Primers: Improves sandability by 30% in nitrocellulose (NC) systems with ≥40% solids, facilitating smoother post-processing of wood primers.
Electronic Potting: Limits bubbles to ≤0.01% in PU encapsulants with ≥50,000 mPa·s viscosity, ensuring reliable protection and performance in electronic potting applications.
