SKYSIL HYDROPHOBIC SILICA S17
1. Ultra-High Specific Surface Area (≥160 m²/g) – A Performance Multiplier
• Defoamer: Increases adsorption capacity at the air-liquid interface, extending foam suppression time to ≥180 minutes, a 50% improvement
over conventional products.
• Lubricant: Enhances extreme pressure and anti-wear film formation, but requires a dispersant to prevent gelation.
2. Deeply Hydrophobic Treatment (Loss on Ignition ≤8.0%)
• 8% Loss on Ignition corresponds to a 4-6 wt% dimethylsiloxane coating (TGA 400°C weight loss step), resulting in: Water contact angle
>130°: Instant penetration of aqueous foam films (bubble break time ≤3 seconds). Improved oil resistance: Hydrophobicity retention >90%
after 1000 hours of service in 150°C gear oil.
3. Low Tap Density (120-140 g/L) – A Process Revolution
• Fluffy structure improves dry powder mixing uniformity (RSD <5%). • Reduces air bubble rate to 0.3% during high-speed dispersion in
lubricants.
4. Strict Purity Contr…
