  • Process for coating metallic surfaces of substrates and articles coated by this process
    Patent number: 11389823
    Abstract: A method for coating metallic surfaces of substrates with surfaces of aqueous (coating) compositions in the form of a dispersion and/or a suspension containing at least one stabilized binder and a gelling agent, the cations having been dissolved out of the metallic surface of the substrate in a pretreatment stage and/or during the contacting. The invention further relates to such a coating based on an ionogenic gel, in which the coating is formed by a process further described herein.

  • BINDERS STABILIZED IN AN AQUEOUS PHASE
    Publication number: 20190300722
    Abstract: Binders stabilized in an aqueous phase and capable of codeposition with ionogenic gel-formers are disclosed. The binder may be a resin or polymer, including polyacrylates, polyurethanes, polyepoxides, urethane acrylates, aromatic and (cyclo)-aliphatic epoxy acrylates, polyesters, and mixtures thereof. The binders are modified by reactions between reactive groups on the binder and hydrophilic, functional molecules. Reactive groups on the binder may include isocyanates, hydroxyls, carboxyls, oxiranes, vinyls and amines. A method of producing such dispersions is disclosed.

  • Method for removing substrates provided with organic coatings
    Patent number: 10040955
    Abstract: The invention relates to a method for removing a substrate that is coated with an organic coated coating by means of ionogenic gel formation. In said method, a wet or dry organic coating that has not yet formed a film on the substrate is treated with an aqueous solution of a metal salt from main group I in the periodic table of the elements, a complexing agent and/or a basic compound having a pH value >10.
