Min-U-Gel 400 Magnesium aluminum silicate ITC Industrials-Floridin Rheology Modifiers / Thickeners >> Organoclay >> Attapulgite ADHESIVE >> Water-based SEALANT MIN-U-GEL® 400 is a hydrous magnesium aluminum silicate with gelling and rheological properties used to thicken and stablize aqueous systems. MIN-U-GEL® can be used alone or in conjunction with associative thickeners where a low shear thixotrope is needed to support the high shear thixotropy of the associative thickener. Used in sealants and caulks and water-based adhesives. Hydrous magnesium aluminum silicate with gelling and rheological properties. Used to thicken and stablize aqueous systems.
