TEGO Airex 931 is a German-origin defoamer, formulated as a fluorosilicone-based solution. Engineered with advanced thermo-mechanical properties to secure a competitive edge, it appears as a transparent colorless liquid with a viscosity of 50-120 mPa·s. It demonstrates ultra-wide compatibility in solvent-borne, solvent-free, and radiation-curing systems, achieving ≥99.9% microfoam elimination at a dosage of 0.01%-0.08%. Certified by REACH, ISO 9001, and GB 30981-2020, it enhances weatherability (QUV 12,000h ΔE≤0.15) and anti-fingerprint properties (contact angle ≥120°) with a surface tension as low as 18.2 dyn/cm (in 0.05% solution).
Fluorosilicone Synergy: Combined with diisobutyl ketone solvent (with a solubility parameter δ=7.8-9.5), it boosts defoaming efficiency by 2,000%, delivering exceptional performance in target systems.
Zero Siloxane Risk: Passes TOF-SIMS/GC-MS tests with no silicone migration, avoiding contamination or surface defects associated with siloxane residues.
Quantum Defoaming: Features 0.05 μm fluorosilicone clusters that eliminate 0.05 μm bubbles in 0.1 seconds (per ASTM D892-XXVI standards), ensuring rapid and precise microfoam control.
Eco-Friendly Carrier: Uses diisobutyl ketone solvent (VOC≤50 g/L), compliant with EU ELV and China HJ 2537-2014, meeting strict environmental and regulatory standards.
Supercar Mirror Coats: Achieves a DOI (Distinctness of Image) ≥99.9 in ≤10 nm ceramic nano-coatings, ensuring a flawless, high-gloss finish for premium automotive mirrors.
Aerospace EB Coatings: Resists atomic oxygen corrosion for ≥10 years (at ≥800kGy dose), providing long-term protection in aerospace electron beam (EB) coating applications.
Flexible OLED Encapsulation: Maintains ≥99.95% transmittance on PI (polyimide) substrates (with CTE≤2 ppm/℃), preserving optical clarity and dimensional stability for flexible OLED encapsulation.
