Expert Selection FAQ
Comparison: Precipitated vs. Fumed Silica
Precipitated Silica Wet Process
Manufacturing Chemical precipitation from sodium silicate solution with sulfuric acid.
Structural Morphology Porous, larger secondary particles with high surface hydroxyl groups.
Core Applications
Toothpaste Green Tires Anti-Caking
Fumed Silica Dry Process
Manufacturing Flame hydrolysis of silicon tetrachloride (SiCl4) in an O₂/H₂ flame.
Structural Morphology Non-porous, ultra-fine primary particles forming chain-like aggregates.
Core Applications
Coatings & Inks Sealants Adhesives
+Why use Precipitated Silica as a Matting Agent?
01
High Matting Efficiency
Engineered pore volume maximizes light scattering, achieving a dead-matte finish with lower dosages.
02
Superior Optical Clarity
Refractive index matched to common resins (approx. 1.46) to ensure deep, transparent finishes without milkiness.
03
Precision Haptics
Strict particle size distribution (D50) provides a smooth, soft-touch surface ideal for premium wood and leather.
04
Scratch & Mar Resistance
Wax-treated grades reduce the Coefficient of Friction (COF), protecting surfaces from burnishing and mechanical wear.
05
Anti-Settling Properties
Surface-modified particles ensure “soft settling,” allowing for easy re-dispersion even after long-term storage.
06
Chemical Inertness
Provides excellent UV stability and resistance to household chemicals without affecting coating adhesion.
