Patent ID: 8475599

Claim:
A method for using a solution for cleaning a substrate, comprising: providing a solution in a container, the solution being mixed from at least a continuous medium, a polymer material, and a solid material, the polymer material in the solution imparting a finite yield stress to the solution, such that the solution is maintained in a stable elastic gel form, the stable elastic gel form being configured to hold the solid material in place and prevent the solid material from moving in the solution and forming sedimentation if stresses less than the finite yield stress is imparted on the solution after synthesis of the solution and during any storage of the solution; applying at least a minimum shear stress on the solution, the minimum shear stress being at least greater than the finite yield stress so that the stable elastic gel exhibits fluid-like behavior; flowing the solution from the container after imparting the minimum shear stress, the solution that is flown from the container has a mixed consistency of the solid material in the solution; and applying the solution to a preparation system for application to a surface of the substrate.
