TEGO Foamex 932 Defoamer

TEGO Foamex 932, a German fluorosilicone nanocomposite, is a pale yellow transparent liquid with 80-300 mPa·s viscosity. It stays active stably under ≤150°C and extreme shear (≥5,000 s⁻¹), suppressing 95% of foam at 0.05%-0.2% dosage. Certified by REACH, ISO 9001 and GB 24409-2020, it boosts distinctness-of-image (DOI≥98) and anti-sagging in automotive OEM paints and two-component PU wood coatings.

Features Of TEGO Foamex 932 Defoamer

  1. Fluorosilicone Synergy: Fluorocarbon chains (≤15 mN/m) collapse bubbles within 5 seconds (per ASTM D892-IX).

  2. High-Temp Baking Stability: Viscosity change ≤1.5% after 150°C/30min curing.

  3. No Surface Imperfections: Reaches ≤0.01 craters/m² in clearcoats with ≥50% solid content.

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

  5. Cost-Saving: Cuts usage by 60%, saving ¥280-350/ton.

Typical Applications Of TEGO Foamex 932 Defoamer

  1. Automotive Basecoats: Controls metallic flake orientation with ΔL≤0.3.

  2. Solid Wood PU Coatings: Removes sanding marks to ≤1 grade (ASTM D5178).

  3. Heavy-Duty Baking Paints: Endures ≥1,500h salt spray in amino-alkyd systems.

  4. Piano Lacquers: Achieves ≥100 GU (60°) gloss with orange peel wavelength ≥10mm.
