TEGO Airex 936 Defoamer

TEGO Airex 936, a German fluorosilicone nanocomposite, is an amber transparent liquid with 150-500 mPa·s viscosity. It remains stably active under ≤130°C and extreme shear (≥8,000 s⁻¹), curbing 97% of foam at 0.1%-0.3% dosage. Certified by REACH, ISO 9001 and GB 24409-2020, it boosts leveling (Ra≤0.08 μm) and anti-sagging in two-component PU wood coatings and amino-alkyd industrial finishes.

Features Of TEGO Airex 936 Defoamer

  1. Wood-Tailored Formula: 0.3 μm fluorosilicone particles clear spraying bubbles in PU systems (NCO% 6-12%).

  2. Versatile Process Fit: Works with airless spray (≥200 bar), roller (≤20 m/min) and brush application.

  3. High-Temperature Stability: Viscosity change ≤1.2% at 130°C/20min curing.

  4. No Surface Flaws: Reaches ≤0.005 craters/m² in clearcoats with ≥55% solid content.

  5. VOC Compliance: Benzene-free solvent system meets HJ 2537-2014 standards.

Typical Applications Of TEGO Airex 936 Defoamer

  1. Solid Wood PU Coatings: Enhances sandability by 40% (ASTM D5178 ≤0.5 grade).

  2. Parquet Floor Finishes: Cuts drying time by 25% in UV primers (≥300 mJ/cm²).

  3. Heavy-Duty Enamels: Endures ≥2,000h salt spray in amino-alkyd systems.

  4. Decorative Metal Paints: Achieves ≥105 GU (60°) gloss with DOI≥97.
