The invention relates to a binding dispersion for the production of insecticide paints and to a method for producing said dispersion, consisting of an aqueous dispersion of modified VeoVa vinyl nature, including active biocide materials, in which the polymer is vinyl acetate and VeoVa and the biocide materials, at a concentration of 10%, are immersed to surround the polymer particles, forming a structure with a polymer core and a shell of active ingredients. The production method comprises: a seeding step, in which a small part of the pre-emulsion (monomers, emulsifiers, water) and catalyst is added to the reactor a polymerization step, in which the rest of the catalyst and pre-emulsion is then added, followed by the active biocide materials stirring at high temperatures for at least one hour and a redox reaction, with oxidizing and reducing agents.
