Abstract
An aqueous surface treatment composition, methods for the production thereof, and an apparatus for the preparation of aqueous surface treatment compositions. The composition comprises a water soluble thickening polymeric thickening agent, water and a basic neutralizing agent. Additionally, coloring agents and polyols may be added to the composition. The polymeric water soluble thickening agent and basic neutralizing agent are present in sufficient quantity to afford a viscous composition that, upon application to a suitable surface, provide a surface treatment. The apparatus useful for the production of aqueous surface treatment compositions simultaneously and rapidly mixes and dispenses a fast forming viscous compositions.
