SUBSTRATE WITH ANTIMICROBIAL PROPERTIES AND PROCESS FOR THE PRODUCTION OF AN ANTIMICROBIAL SUBSTRATE

摘要

A process for the production of a substrate having antimicrobial properties is described and a substrate. It comprises a step consisting of the deposition of a metal non-gelling layer comprising an inorganic antimicrobial agent; and a step consisting of the diffusion of the agent into said at least one exposed surface of the substrate by thermal treatment. Alternatively, the substrate may be first coated with an underlayer and the diffusion occurs in the underlayer. Substrates having antimicrobial properties are also described. In particular, a substrate exhibiting a bactericidal activity measured in accordance with standard JIS Z 2801 of higher than log 2. In particular tempered glass maintaining antibacterial properties after accelerated ageing tests are obtained.
