A method for production of an additive case having the steps of preparing a zinc oxide concentration from a paste of nanometric zinc oxide that was previously subjected to surface treatment based on silane additives, preparing a silver concentrate starting from a silver paste of nanometric metallic silver, and preparing the additive paste by mixing the zinc oxide concentrate and the silver concentrate and a polymeric carrier with a compatible resin. The polymeric carrier and compatible resin are in a proportion of between 10:90 to 90:10. The steps obtains the additive paste of ZnO/AG° in masterbatch in pellet form.
