Attapulgite is a hydrated magnesium aluminosilicate having the ideal formula: 3MgO - 1.5 Al2O3 - 8SiO2 - 9H20.
Attapulgite occurs as packed bundles of submicron particles whose needle like structure gives it unique colloidal properties. In nature, Attapulgite occurs with impurities such as carbonate minerals and quartz. Zigma, with its experienced mineral and process specialists, produces Attapulgite clay with the least amount of impurities with tight process controls and rigorous QC processes.
ZIG-GEL 50 is a specially processed Attapulgite that disperses easily in water and solvent???borne systems and is used for viscosity modifications for stable suspensions. ZIG-GEL 50 is the perfect suspending agent that can hold dense or large particles in suspension for an extended period1.
