Many adhesives and coatings rely on the addition of modifiers for viscosity and rheology. Shear force created within the mixing container will quickly and easily deagglomerate modifiers such as fumed silica, carbon black, cotton flock, carbonaceous materials, microspheres, etc, and has been found to more effectively wet out high surface area fillers. If optical clarity is an important factor in the final product, vacuum mixing can quickly clarify material by removing adsorbed air or moisture.
