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).
Superhydrophobic & Fast Defoaming: 0.18 μm hybrid particles clear bubbles in 1 second (per ASTM D892-XIII).
Strong Tolerance: Stable in 150°C/2h baking (viscosity change ≤0.8%) and when immersed in pH 1 acid.
Marine-Level Protection: Triples salt spray resistance in ≥85% solid chlorinated rubber/epoxy systems.
No Silicone Migration: Passes FTIR/GC-MS residue tests.
Highly Concentrated: Cuts usage by 90%, saving ¥500-800/ton.
Ship Antifouling Paints: Lowers friction by 15% in ≥90% solid chlorinated rubber coatings.
Automotive Baking Primers: Reaches DOI≥97 after 180°C/30min curing.
Acid Pickling Tanks: Controls foam in ≥40% H2SO4/HF solutions for at least 6 months.
Petrochemical Tank Linings: Keeps porosity ≤0.003% in ≥200°C-resistant phenolic epoxy.
