BET 230–260 m²/g · DBP 220–320 — dual-use ultra-fine silica for paint matting and general-purpose reinforcement
SN-CT-102 is a precipitated silica that combines paint/ink matting and general ultrafine SiO₂ functions. With an average particle size of 5 μm, high BET (230–260 m²/g) and 1.4–1.5 ml/g pore volume, it delivers matting and smooth-touch finishes in decorative, wood, furniture and powder coatings. SiO₂ 98.5% with neutral pH (6.9–7.1) enables stable dispersion in both solvent- and water-based systems.
Key Features
- 🧱 Synthetic Amorphous SiO₂ — Pure white amorphous powder produced by reacting soluble silicate with acid
- 🧪 High-Purity Management — SiO₂ ≥ 98–99%, with strict control of harmful components such as heavy metals, lead, and arsenic
- ⚙️ Porous Structure — High specific surface area and oil absorption deliver reinforcement, thickening, matting, and adsorption performance
- 🌿 Wide Applications — Applied across industries: rubber, paint, plastics, food/pharma, toothpaste, cosmetics, and more
