The present invention has an object to efficiently precipitate a paint residue. A system (10) of collecting a paint residue includes: a bubble-containing functional water generation portion (6) which is configured so as to generate functional water that is bubble-containing alkaline water or acid water; a paint collecting portion (1) which collects the paint residue with the functional water; and a storage portion (2) which recovers the functional water from the paint collecting portion and which stores the functional water.

Methods and compositions useful for cleaning the lines used during manufacturing processes are disclosed. In certain embodiments, the methods and compositions may be particularly useful in the manufacture of colored paints or coatings or in the use of colored paints or coatings, for example, in the manufacture of finished automobiles.

A device, method, system, operating method, component and composition are disclosed for preventing deposits of a disposal agent, e.g., where a multi-component paint having two or more components such as a paint component and a hardener component, is employed, for example in a coating installation. Exemplary illustrations include a receiving device for disposal agent, e.g., for disposal agent from cleaning and/or rinsing processes of an application apparatus, comprising at least one inlet opening for introducing the disposal agent, and an outlet opening for removing the disposal agent. Furthermore, at least one loading means may be provided in order to load the receiving device with a loading agent, which may at least delay a deposition of disposal agent on or in the receiving device.

Coating installations are provided that include storage tanks for an aqueous base component and a non-aqueous hardener component, circulation lines for the components from the respective storage tanks, a mixer and an entrance to the mixer with a connection between each circulating line and the entrance to the mixer, and a release valve for the non-aqueous hardener component. The coating installation downstream of the non-aqueous hardener release valve is filled with a non-aqueous solvent composition comprising 0 to 10 wt. % of N-alkyl pyrrolidone, 0 to 5 wt. % of dimethyl sulfoxide, 10 to 50 wt. % of γ-butyrolactone, 10 to 50 wt. % of at least one monoalcohol, 10 to 60 wt. % of at least one organic solvent inert towards isocyanate groups, other than γ-butyrolactone, other than N-alkyl pyrrolidone, and consisting of carbon, hydrogen, oxygen and, optionally, nitrogen, and 0 to 10 wt. % of at least one additive.

The present invention is directed towards compositions, systems, and methods for treating contaminants from wastewater streams using cyclodextrin and/or a cyclodextrin derivative. Also disclosed herein is the use of a cyclodextrin, a cyclodextrin derivative, or a combination thereof as a detackifying and/or flocculating agent.

Two-part aqueous coating compositions as well as methods of using thereof are described. The first coating component can comprise one or more polymers and the second coating component can comprise a flocculant. The first coating component and the second coating component can be provided as separate aqueous compositions. The first coating component and a second coating component that can be co-applied (e.g., simultaneously or sequentially) to a surface form a rapid set coating.

The present disclosure provides stable, low chloride paint detackifier compositions. Also disclosed are methods of making the paint detackifier compositions and methods of using the paint detackifier compositions. The detackifier may be made from cationized starch and sodium aluminate. The starch can be wheat starch, corn starch, tapioca starch, potato starch, rice starch, sweet potato starch, sago starch, mung bean starch, arrowroot starch, and any combination thereof.

Two-part aqueous coating compositions as well as methods of using thereof are described. The first coating component can comprise one or more polymers and the second coating component can comprise a flocculant. The first coating component and the second coating component can be provided as separate aqueous compositions. The first coating component and a second coating component that can be co-applied (e.g., simultaneously or sequentially) to a surface form a rapid set coating.

A method for treating a circulating water in a wet paint booth, the method including adding a treatment agent including an aqueous solution including a tannin and an alkali metal hydroxide and/or an alkali metal carbonate to the circulating water in any of passages for the circulating water in the wet paint booth, wherein the passages include for supplying the circulating water from a water tank to a paint booth, for collecting an uncoated paint in the circulating water, and for returning the circulating water to the water tank; to detackify the uncoated paint collected in the circulating water.

To efficiently perform an adhesion reduction treatment of water that circulates through a wet paint booth which contains a solvent-based paint by adding a relatively small amount of chemical to the water without the need for another chemical except that the alkaline chemical is used for pH adjustment, that is, with only one chemical. An aluminum salt having a basicity of 60% or more and an alkaline chemical are added to water that circulates through a wet paint booth which contains a solvent-based paint. An adhesion reduction treatment of the solvent-based paint is performed at a pH of 7 or more and is preferably performed at a pH of 7.5 or more. Using a powder mixture produced by mixing a powder of the aluminum salt with a powder of the alkaline chemical facilitates the treatment.
