Problems solved by technology
This process presents additional difficulties due to the need for the individual products to first interact in relatively fixed proportions to effectively detackify and collect paint solids
Achieving the continuation of this necessary balance is made more difficult by investing the above substances separately

Embodiment 1
[0038] This example demonstrates the effectiveness of compositions of the present invention prepared by the aforementioned treatment "A".
[0039] paint
Embodiment 2
[0041] The examples that follow demonstrate the importance of each component in the performance of the invention. In Example 2, the polymer component has been removed, leaving only cationic starch and aluminum hydrochlorate (ACH). (In this and subsequent examples used, the amount of residual chemical constituents was increased to maintain an equal amount of active solids for all tests.)

Abstract
The current invention relates to a composition and a method for treating impurities in a circulating water system. The circulating water system impurities may be oversprayed paint in paint spray booth applications. The composition includes an aqueous solution of a cationized starch, a polybasic aluminum salt such as aluminum chlorohydrate or polyaluminum chloride and a solution of a medium to high MW aqueous flocculant. The composition is particularly useful when added to recirculating scrubber water in paint spray booths for effectively treating both water based and solvent based paints.
Description
technical field [0001] This invention relates to improved separation of paint and spray residues from water streams in the paint and finishing industry. The present invention achieves improved anti-stick action and slurry separation, while also being a "greener" new technology that substantially reduces its environmental impact. Background technique [0002] The painting process of car bodies, engines, and a variety of industrial and consumer products takes place in dedicated spaces called paint booths. These spray booths provide a controlled work area for painting operations that not only enhances worker safety, but also minimizes potential contamination that could be detrimental to the final painting job. The size and design of a paint spray booth can vary significantly, but all include the work area where the actual painting process is done and the backend / floor area where the overspray paint is removed from the air. In small or low production systems, the overspray rem...
