Description

C09C covers physical and chemical treatment methods applied to inorganic materials to improve their performance as pigments or fillers in paints, coatings, plastics, and related compositions. This includes surface modification, coating, grinding, and purification of mineral pigments and fillers, as well as the synthesis and processing of carbon black from carbonaceous sources. The subclass excludes fibrous fillers (covered elsewhere) and focuses on particulate inorganic solids that enhance color, opacity, or mechanical properties of end-use formulations.

Scope Notes

Limiting references: Treatment of materials specially adapted to enhance their filling properties in mortars, concrete or artificial stone , ,
