Geotex® 40-200

Geotex® 40-200 is a high purity, granular calcium carbonate produced from a high brightness marble deposit in Georgia with a controlled particle distribution. The controlled particle distribution allows G40-200 to be used as a texturizing agent, in plaster, EIFS, in abrasives, PVC flooring, and oilfield drilling fluids where its low acid insoluble content is useful.
