Features and Benefits

VOK®- AP 7303 is a rheological agent that transcends the traditional organic compound and changes its name to silicate (organic bentonite) Traditional organic compounds renamed silicate need high shear and polar activator to help disperse. In contrast, VOK®- AP 7303 can be easily added and activated in solvent and resin under medium shear. It has good pseudoplasticity. Use VOK®-AP 7303  The formulation of has high viscosity at low shear, so it has good anti sedimentation and anti water separation effects. The shear force during construction makes the viscosity drop sharply and the workability increases
