TEGO Foamex 1488, a silicone-polyether nanocomposite waterborne emulsion, is a milky homogeneous liquid with 250-600 mPa·s viscosity. It stays stably active under pH 4-10 and ≤70°C, curbing 65% of foam at 0.05%-0.15% dosage. Certified by REACH, ISO 9001 and GB 18582-2020, it improves anti-blocking (no adhesion at 60°C/24h) and printability (dot gain ≤1.2%) in styrene-acrylic systems and UV varnishes.
Wide Compatibility: Stable in styrene-acrylic (Tg 20-50°C) and EVA (45-65% solids) systems.
Nano-Scale Action: 1.2 μm silicone particles clear foam in 8 seconds (per ASTM D892-IV).
No Migration: Passes EN 71-3 toy safety standard for residue.
Process Adaptability: Works with ≤5 μm bead milling and ≥2,000 rpm dispersion.
Cost-Effective: 40% lower dosage than conventional defoamers.
Architectural Elastic Coatings: Increases tensile strength by 25% in 55-70% PVC systems.
Gravure Lamination Inks: Reduces trailing ΔE≤0.3 on BOPP at ≥400 m/min.
Wood Sealers: Controls bubbles ≤0.5/cm² in NC systems with ≥30% solid content.
Asphalt Coatings: Enhances crack resistance at -20°C in polymer-modified asphalt.
