GENERAL INFORMATION GEL 436P is a finely ground, high quality attapulgite clay that is used to impart thixotropic properties to aqueous media. The material provides excellent low shear viscosity and suspension properties in water and other polar liquids. GEL 436P is not affected by high concentrations of dissolved electrolyte. Stable, high quality and finely ground attapulgite clay (hydrous magnesium aluminium silicate). Used to build viscosity and suspension properties in adhesives and sealants.
