TEGO Foamex 30 Defoamer

TEGO Foamex 30, a German polyether-silicone/fumed silica nanocomposite, is an amber translucent liquid with 300-800 mPa·s viscosity. It works stably under pH 2-12 and ≤150°C, suppressing 99% of foam at 0.03%-0.15% dosage. Certified by REACH, ISO 9001 and GB 30981-2020, it boosts salt spray resistance (≥5,000h) and hydrophobicity (contact angle ≥120° in relevant systems).

Features Of TEGO Foamex 30 Defoamer

  1. Superhydrophobic & Fast Defoaming: 0.18 μm hybrid particles clear bubbles in 1 second (per ASTM D892-XIII).

  2. Strong Tolerance: Stable in 150°C/2h baking (viscosity change ≤0.8%) and when immersed in pH 1 acid.

  3. Marine-Level Protection: Triples salt spray resistance in ≥85% solid chlorinated rubber/epoxy systems.

  4. No Silicone Migration: Passes FTIR/GC-MS residue tests.

  5. Highly Concentrated: Cuts usage by 90%, saving ¥500-800/ton.

Typical Applications Of TEGO Foamex 30 Defoamer

  1. Ship Antifouling Paints: Lowers friction by 15% in ≥90% solid chlorinated rubber coatings.

  2. Automotive Baking Primers: Reaches DOI≥97 after 180°C/30min curing.

  3. Acid Pickling Tanks: Controls foam in ≥40% H2SO4/HF solutions for at least 6 months.

  4. Petrochemical Tank Linings: Keeps porosity ≤0.003% in ≥200°C-resistant phenolic epoxy.
