Key Features
  • 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.
  • Optigel WH is a very economical thixotrope. Optigel WH is a fraction of the cost of most cellulosic thickeners. Optigel WH contributes to excellent spray atomization properties.
