Gel 460P Magnesium aluminium silicate 12174-11-7 Zemex Industrial Minerals Extenders / Fillers >> Aluminium silicate Rheology Modifiers / Thickeners >> Organoclay >> Attapulgite ADHESIVE >> Water-based SEALANT GEL 460P is a finely ground attapulgite clay (hydrous magnesium aluminum silicate. GEL 460P is used to build viscosity and suspension properties in paints, adhesives, sealants, and foundry coating systems. GENERAL INFORMATION GEL 460P is 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. The performance of the material is not affected by 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.
