BET 150 m²/g · hydrophobic-treated — anti-settling in paints, cosmetics
SN-FCT-151 is a hydrophobic-treated fumed silica grade (BET 150 ± 25 m²/g) used for anti-settling of pigments in solvent-borne paints, and thixotropy in silicone rubber and cosmetics. SiO₂ ≥ 99.98% and carbon content 0.6–1.2% provide strong hydrophobicity and dispersion in non-polar media.
Key Features
- 🔬 Ultra-High SSA Amorphous SiO₂ — Ultra-fine non-crystalline silicon dioxide with BET 100–400 m²/g — molecular activity at the nanoparticle scale
- 🧪 High Purity (≥99.8%) — Produced by flame hydrolysis of silicon tetrachloride (SiCl₄) with trace metal impurities at ppm levels
- ⚙️ Powerful Thixotropy — Forms 3D network structures that dramatically improve viscosity and thixotropy of liquids
- 💧 Hydrophilic & Hydrophobic Grades — Hydrophilic and hydrophobic grades available depending on surface treatment
- 🔥 Heat & Chemical Resistance — Stable under high temperatures, acids, alkalis, and organic solvents — suitable for harsh processes
- ✨ Excellent Reinforcement & Thickening — Simultaneously improves mechanical strength and processability of silicone rubber, adhesives, and sealants
