Geotex® 30-50 is a high purity, granular calcium carbonate produced from a high brightness marble deposit in Georgia with a controlled particle distribution. In applications needing high brightness material such as plaster and stuccos, Geotex has outstanding performance. The marble crystal structure is useful in recirculation drilling fluids.

Functions: Filler, Slip Control Agent

Chemical Family: Calcium Salts, Carbonates, Mica

Particle Size: 415.0 - 415.0 microns
