Abstract: Adhesive polymers are formed when polyvalent azides and alkynes are assembled into crosslinked polymer networks by copper-catalyzed 1,3-dipolar cycloaddition. The condensation polymerization is efficiently promoted by Cu ions either leached from the metal surface or added to the monomer mixture, and strong interactions with metal surfaces are provided by the multiple triazole binding elements produced. The adhesive polymers may be formed either as adhesive polymer coatings or as adhesive polymer cement.

Abstract: A composition and method is described for providing conformal protective or decorative polymer coatings on metals such as aluminum, copper, iron, steel, zinc, and their formation by dip autopolymerization. In accordance with the present invention, an acidic solution of organic monomer undergoes autopolymerization upon contact with a metal substrate, thereby forming a polymeric coating on the substrate. The method comprises providing the acidic monomer solution, dipping the metal substrate to be coated for a prescribed period of time depending on the thickness of the coating desired, and then removing the substrate from the solution. Importantly, the polymerization requires no application of external driving force, such as thermal or electrical energy. The coatings thus formed are up to 50 microns thick, and conform to the shape of the substrate. These coatings further have uniform thickness, and excellent thermal stability and protective properties. In one preferred embodiment of the present invention, the composition comprises an acidic solution of an organic electron acceptor monomer that undergoes autopolymerization in contact with a metal substrate, thereby forming a polymeric coating on the substrate. In another preferred embodiment of the present invention, the composition comprises an acidic solution of an organic electron acceptor monomer and an organic electron donor monomer that undergo autopolymerization in contact with a metal substrate, thereby forming a polymeric coating on the substrate. Metal-polymer composites are also described.

Abstract: An effective electrically insulating film on the surface of a metal object, such as a common type of electric motor core assembly, in which the surface includes an interior comer on which insulation is desired, can be formed by autodeposition with an adequate thickness in the interior corner without need for excessive thickness on other parts of the surface that are more readily covered by prior art methods of applying an insulating coating. If the autodeposition composition used includes as its primary film-forming component a copolymer of certain acrylic monomers, a very high volume resistivity can be achieved.

Abstract: The susceptibility to heat degradation of an autodeposited coating in which the principal organic constituents are copolymers of vinylidene chloride in which vinylidene chloride residues constitute at least half the weight of the total binder phase in the autodeposited coating is improved if the wet autodeposited coatings are rinsed, before being later dried and cured, with a water-based liquid rinse that comprises dissolved phosphate ions in a concentration that corresponds stoichiometrically to at least 0.5 g/l of tripolyphosphate ions. The water-based liquid rinse preferably has a strongly alkaline pH and also comprises dissolved organic molecules that are effective chelating agents for dissolved iron cations by reason of having in each molecule at least two carboxyl, carboxylate, and/or other hydroxy moieties.

Abstract: The use of selected cation exchange resins to remove dissolved multivalent cations ions such as iron, zinc, and chromium from used autodeposition compositions permits reuse of the autodeposition compositions without the need for added surfactant and without developing any undesirable graininess or other texture in the coatings formed. Iminodiacetate cation exchange resins are very effective for removing iron ions when they are the only multivalent ions to be removed, and can be efficiently regenerated with 0.5 to 4% by weight aqueous hydrofluoric acid. By proper choice of other cation exchange resins and operating conditions, zinc can be selectively extracted from autodeposition baths containing both iron and zinc, and either iron or zinc can be selectively displaced from the loaded ion exchange resin.

Abstract: An automated system is disclosed for providing at least periodic removal of metal ions from a chemical complex and contaminants from a chemical bath. The chemical bath is a latex solution containing charged latex particles and having an acidic pH to form a coating by autodeposition, the charged particles tending to coagulate when subjected to a high shear circulation. The system uses an ion exchange column containing an iminodiacetate ion exchange resin for removal of the metal ion contaminants. The chemical bath is passed through the ion exchange column at a low velocity to prevent coagulation of the latex particles. Conductivity measurement devices and controllers are used to automate the operation of the system. Also, additional sensors, such as pressure and level sensors, controllers, filters, circulation pumps and tanks are used for performing rinsing and regeneration of the ion exchange column.

Abstract: Pinhole and blister formation during autodeposition coating of galvanized steel and similar zinciferous surfaces can be greatly reduced by exposing the zinciferous surfaces to a pinhole inhibiting aqueous HF solution containing a suitable additive before using an autodeposition process itself. The most effective additives are boric acid, polyphosphonic acids, and polyethyleneimine.
