Gel 601P Magnesium aluminium silicate 12174-11-7 Zemex Industrial Minerals Extenders / Fillers >> Aluminium silicate Rheology Modifiers / Thickeners >> Organoclay >> Attapulgite ADHESIVE >> Water-based SEALANT GEL 601P is a finely ground attapulgite clay (hydrous magnesium aluminum silicate.GEL 601P is widely used to build viscosity and gel structure in paints, adhesives, sealants and foundry coating systems. GENERAL INFORMATION GEL 601P is finely ground, high quality attapulgite that is used to build viscosity and gel structure in 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.
