Data source. Values in bold for VS660, VS1650A and VS3851 are measured results from batch 260716 (sampled 2026-07-16), tested to HG/T 3061-2020. A batch COA is issued with every shipment and is available on request before ordering.
Particle size, BET surface area and oil absorption for all grades are the production specification ranges from the manufacturing data sheet, updated 13 September 2026. Oil absorption is reported by the DBP method in mL/100 g throughout. Particle size is measured by laser diffraction (ISO 13320). Bulk density for measured grades is tamped density in g/cm³ converted from g/L. Confirm the current specification for your grade before formulating.

Parameter Guide
Particle size
Particle size by laser diffraction (ISO 13320), in µm. Values are the production specification range for each grade. The same range is published on the product range page.
Pore Volume
Pore volume by nitrogen desorption, in mL/g. Higher pore volume generally means more efficient gloss reduction at a given particle size, and a greater influence on system viscosity.
BET Surface Area
Specific surface area by N₂ adsorption (BET method), in m²/g. Values are the production specification range for each grade. Across the range: 170–600 m²/g.
Oil Absorption
Oil absorption by the DBP method, reported in mL/100 g (ISO 787-5 principle). Correlates with BET surface area. Higher value = greater impact on system viscosity and matting efficiency.
Loss on Ignition
Loss on ignition (%), measured by calcination. Reflects surface treatment level and bound organics; higher values indicate a more heavily treated surface.
Moisture Content
Loss on drying at 105 °C (%), reported as the specification maximum. Excess moisture causes agglomeration and hard-packing in storage.
Bulk Density
Loose bulk density (g/cm³). Finer powders: 0.27–0.33. Coarser grades: 0.37–0.44. Affects packaging volume and shipping cost.
Whiteness
Hunter whiteness / ISO R457. Critical for transparent and light-colored coatings. All Vistamatt grades ≥92.
