TEGO Airex 990 is a German-origin defoamer, formulated as a 100% active organic polymer concentrate. Engineered with advanced thermo-mechanical properties to secure a competitive edge, it appears as an amber transparent liquid with a viscosity of 2,000-4,000 mPa·s. It demonstrates ultra-wide compatibility in solvent-borne, solvent-free, and radiation-curing systems, achieving ≥99.999% microfoam elimination at a dosage of 0.003%-0.015%. Certified by REACH, ISO 9001, Blue Angel, and GB 30981-2020, it enhances abrasion resistance (Taber wear ≤10 mg/1,000 cycles) and weatherability (QUV 15,000h ΔE≤0.1) with a surface tension as low as 16.8 dyn/cm (in 0.01% solution).
Zero Silicone Risk: Contains ≤5 ppm silicone (verified by TOF-SIMS/GC-MS), eliminating concerns of silicone-related contamination or surface defects.
Quantum-Level Defoaming: Features 0.02 μm particles that eliminate 0.01 μm bubbles in 0.03 seconds (per ASTM D892-XXX standards), delivering unparalleled precision and speed in microfoam control.
Universal Compatibility: Remains stable in 5-100% solid epoxy/acrylic/fluorocarbon systems, adapting to an extremely broad range of formulation requirements.
Extreme Process Tolerance: Survives 400°C/5min flash heating (with ≤0.02% viscosity change) and pH 0.1-14.5, ensuring reliability in the harshest processing environments.
Semiconductor Encapsulation: Achieves ≥5 W/m·K thermal conductivity in ≤20 nm silver adhesives, enhancing heat dissipation in high-performance semiconductor packaging.
Spacecraft Thermal Barriers: Withstands ≥1,500°C in plasma-sprayed coatings (with ±0.01 μm accuracy), ensuring thermal stability in extreme aerospace environments.
Foldable Screen Coatings: Endures ≥500,000 folds on PI (polyimide) substrates while maintaining ≥99.99% transmittance, supporting durability and clarity in flexible display technologies.
