TEGO Foamex 20, a German polyether-silicone nanocomposite, is a milky homogeneous liquid with 220-550 mPa·s viscosity. It stays active stably under pH 5-12 and ≤80°C, curbing 94% of foam at 0.08%-0.3% dosage. Certified by REACH, ISO 9001 and GB 18582-2020, it improves leveling (brush mark index ≤0.4 grade) and weather resistance (QUV 1,500h ΔE≤1.0) in water-based architectural coatings and waterproofing systems.
Nano-Scale Defoaming: 0.25 μm hybrid particles clear bubbles within 3 seconds (per ASTM D892-VIII).
Process Compatibility: Works with ≥250 bar airless spray and ≤25 m/min roller coating.
Low-Temperature Stability: No crystallization after 12 months at 5°C (viscosity change ≤3%).
VOC-Free: Meets HJ 2537-2014 standards (VOC ≤1.5 g/L).
Economical: Cuts usage by 45%, saving ¥150-220/ton.
Exterior Elastic Coatings: Limits dirt pick-up to ≤5% in styrene-acrylic with ≥350% elongation.
Bathroom Waterproofing: Reduces drying time by 30% in systems with ≥1.2 MPa penetration.
Concrete Protective Paints: Endures ≥1,000h salt spray in epoxy emulsions with ≥60% solid content.
Floor Sealing Primers: Reaches ≥95% pore filling in solvent-free systems with ≥5 MPa adhesion.
