Evonik TEGO Airex 944 is a 100% active organic polymer/silicone hybrid defoamer (1,500-3,000 mPa·s) for solvent/solvent-free systems. It eliminates 99.99% microfoam at 0.005-0.02% dosage while enhancing abrasion/chemical resistance, certified by REACH/ISO 9001/Blue Angel
Nano-Silicone Synergy: 0.5% silicone microemulsion (≤0.08μm) boosts efficiency via steric hindrance (TEM-verified)
Zero Migration: ≤10ppm silicone content (TOF-SIMS/ICP-OES tested)
Ultrafast Defoaming: 0.03μm hybrids remove 0.03μm bubbles in 0.05s (ASTM D892-XXVII)
Process Robustness: Compatible with ≥500kGy EB curing and pH 0.3-14
Cost Efficiency: 98.75% less usage vs conventional defoamers
Nano-Optical Coatings: ≤0.1Ω/sq sheet resistance in ≤5μm silver nanowire films
Aerospace: Maintains solar absorptance α≤0.15 (±0.05μm accuracy)
Flexible Electronics: Endures 200,000+ bends on PI substrates (≥99.9% transmittance)
Marine Antifouling: Reduces friction to ≤0.03 in fluorosilicone systems
