Process for preparing a dispersion of Polymer particles cationicamente anionicamente ionically stabilized or not, in an aqueous medium.

摘要

Procedure for Coating an article by Cathodic or anodic electrodeposition.Consists of: (a) article Cathodic or anodic Immerse in a Polymer dispersion or anionicamente cationicamente stabilized particles, respectively, formed by: 1) put up a modifier Polymer, which includes reactive groups, and is dissolved in a monomer monomers; (2) Or Bab ethylenically unsaturated Monomer, polymerizing, BBB -,Comprising a reactive Group EQUAL or similar to the reactive groups on the polymer perforated; and 3) a Crosslinking agent which comprises complementary reactive groups to the reactive groups of (1) and (2); b) passing an electrical current between the article and a counter electrode.The reactive groups and reactive groups are complementary between hydroxyl groups, carboxyl, amino, epoxy alcoximetilo, and others. The Polymer modifier is an Epoxy Resin; Crosslinking Agent chooses between urea, melamine and benzoguanamina.
