TEGO Foamex 1488 Defoamer

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.

Features Of TEGO Foamex 1488 Defoamer

  1. Wide Compatibility: Stable in styrene-acrylic (Tg 20-50°C) and EVA (45-65% solids) systems.

  2. Nano-Scale Action: 1.2 μm silicone particles clear foam in 8 seconds (per ASTM D892-IV).

  3. No Migration: Passes EN 71-3 toy safety standard for residue.

  4. Process Adaptability: Works with ≤5 μm bead milling and ≥2,000 rpm dispersion.

  5. Cost-Effective: 40% lower dosage than conventional defoamers.

Typical Applications Of TEGO Foamex 1488 Defoamer

  1. Architectural Elastic Coatings: Increases tensile strength by 25% in 55-70% PVC systems.

  2. Gravure Lamination Inks: Reduces trailing ΔE≤0.3 on BOPP at ≥400 m/min.

  3. Wood Sealers: Controls bubbles ≤0.5/cm² in NC systems with ≥30% solid content.

  4. Asphalt Coatings: Enhances crack resistance at -20°C in polymer-modified asphalt.
