OPTIGEL WH is produced from natural, colloidal aluminum silicate by a unique process. The high purity and consistent viscosity of OPTIGEL WH are made possible by our selective mining and rigid process control from the crude ore to the finished product. OPTIGEL WH is thixotropic in nature. It is most beneficial when it is used in combination with other rheological additives to produce the desired rheological properties in a paint system. Suitable co-thickeners include cellulosics, alkali swellables, and urethane thickeners
