TEGO Foamex K8, a German hydrophobic nanocomposite, is a milky homogeneous liquid with 150-400 mPa·s viscosity. It stays stably active under pH 4-10 and ≤70°C, curbing 92% of foam at 0.1%-0.5% dosage. Certified by REACH, ISO 9001 and GB 18582-2020, it improves leveling (brush mark index ≤1 grade) and scrub resistance (≥10,000 cycles) in water-based architectural coatings and emulsion systems.
Eco-Friendly Make: Free of mineral oil and aromatics, holding French A+ indoor air certification.
Hydrophobic Nano Tech: Silica with 145° contact angle clears bubbles in 8 seconds (per ASTM D892-IV).
Long-Lasting Stability: No foam regrowth for 30 days under 40°C/75% RH conditions.
VOC-Free Guarantee: Meets HJ 2537-2014 standards (VOC ≤2 g/L).
Cost-Saving: Cuts usage by 50%, saving ¥150-200/ton.
Interior/Exterior Emulsion Paints: Reaches contrast ratio ≥0.98 in styrene-acrylic systems with ≥45% solid content.
Waterborne Wood Primers: Keeps sanding marks ≤0.8 grade in EVA with ≥2,000 mPa·s viscosity.
Elastic Waterproof Coatings: Limits pinholes in acrylics with ≥400% elongation and ≥720h water resistance.
Cement Texture Coatings: Extends open time to 45 minutes in systems with ≤1.2mm quartz sand.
