Paint with metallic microwires, process for integrating metallic microwires in paint and process for applying said paint on metallic surfaces

Abstract

The present invention relates to a paint with metallic microwires, to the process for integrating metallic microwires to obtain such paint, and to a process for applying said paint on metallic surfaces (1). The process for applying paint is performed in several steps: applying a first coat (2) of primer on the metallic surface; applying on the first coat (2) a second coat (3, 3′) of paint; applying on said second coat (3) an active third coat (4) of a paint containing microwires; and sanding said active third coat (4) with fine grain sandpaper to remove the microwires oriented perpendicular to the plane of the metallic surface; the maximum attenuation frequency of the reflectivity of said electromagnetic radiation being determined within of the range of maximum attenuation frequencies given by the composition of the paint with microwires, and by the thicknesses and dielectric constants of the different coats.
