TEGO Foamex 800, a German polyether-silicone/fumed silica composite defoamer, is a white thixotropic liquid with 800-1,500 mPa·s viscosity. It remains stably active under pH 4-10 and ≤40°C, curbing 70% of foam at 0.1%-1.0% dosage. Certified by REACH, ISO 9001 and GB 30981-2020, it boosts transparency (haze ≤2%) and storage stability in waterborne wood coatings and industrial paints.
Full-Phase Compatibility: Can be added directly during grinding or letdown without pre-dilution.
Safe for Sensitive Systems: No craters in low-viscosity (KU 60-80) or high-solid (≥55%) systems.
Long-Lasting Suppression: Foam regeneration ≤3% in waterborne acrylics (Tg 20-30°C).
Eco-Friendly: APEO/VOC-free, meeting EC 1907/2006 standards.
Versatile in Processes: Works with airless spraying, roller coating and screen printing.
Waterborne Wood Coatings: Reaches ≥90 GU gloss in PU systems with ≥45% solid content.
Parquet Floor Coatings: Keeps pinholes ≤0.1/m² with 5-minute flow time.
Industrial Protective Paints: Endures ≥1,000h salt spray in chlorinated rubber systems.
Flexo Inks: Lowers dot gain ΔE≤0.4 on BOPP at speeds ≥350 m/min.
