TEGO AIREX 962 Defoamer

TEGO Airex 962, a German non-silicone nanocomposite, is a clear to slightly hazy liquid with 180-450 mPa·s viscosity. It works stably under ≤140°C and extreme shear (≥15,000 s⁻¹), suppressing 98% of foam at 0.05%-0.15% dosage. Certified by REACH, ISO 9001 and GB 30981-2020, it boosts leveling (Ra≤0.05 μm) and anti-sagging in high-solids automotive OEM paints and solvent-based spray systems.

Features Of TEGO AIREX 962 Defoamer

  1. Nano-Scale Defoaming: 0.15 μm non-silicone particles clear bubbles in 3 seconds (per ASTM D892-X).

  2. High-Solid Suitability: Stable in 80-95% solid epoxy/PU systems (≥30,000 mPa·s).

  3. Spray Process Compatibility: Works with ≥300 bar airless and ≤150 MΩ electrostatic spraying.

  4. No Silicone Migration: Passes FTIR silicone residue test for electronic-grade coatings.

  5. Cost-Saving: Cuts usage by 65%, saving ¥400-500/ton.

Typical Applications Of TEGO AIREX 962 Defoamer

  1. Automotive Clearcoats: Reaches DOI≥99 in acrylic systems with ≥75% solid content.

  2. Wind Blade Coatings: Endures ≥3,000h salt spray in solvent-free epoxy.

  3. Rail Transit Paints: Shortens curing time by 40% in polyaspartic ester systems.

  4. Marine Container Coatings: Keeps surface roughness Rz≤5 μm in alkyds with ≥50,000 mPa·s viscosity.
