BET 280 m²/g · DBP 360–400 — gel-method matting agent with high dispersibility
SN-CT-107 is a gel-method white precipitated silica matting agent. Its 280 m²/g surface area, DBP 360–400 and 1.8 ml/g high pore volume deliver strong matting and smooth touch in furniture, wood and coil coatings. The 5 μm average particle creates a fine micro-texture that produces glare-free matte finishes.
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
