Publication number: 20220298666Abstract: A process for the making of metallic product with biocidal properties is disclosed, and first comprises anodizing a product having at least one metallic surface (e.g. aluminum, steel) using a controlled current density to form pores on the surfaces with controlled spatial density and depth. The process also comprises contacting the anodized metallic surfaces with a first biocidal solution before sealing the pores. Preferably, the metallic surfaces can be contacted again with the first biocidal solution after the sealing step. A method for reactivating biocidal properties of the metallic products is also disclosed, and comprises contacting again the biocidal product with a second biocidal solution. Preferably, the second solution is less concentrated than the first solution for safety sake. The invention provides a simpler, quicker, cheaper and improved process for treating or reactivating the metallic surfaces in order to obtain a metallic product having superior and enduring biocidal properties.Type: ApplicationFiled: June 9, 2022Publication date: September 22, 2022Applicant: A3 SURFACES INC.Inventors: Maxime DUMONT, Jocelyn LAMBERT, Guy LEBLANC, Martin LAMBERT, Michel LAVOIE, Jean-Pierre COLLARD, Myriam AUCLAIR-GILBERT, Simon GAGNON
