Abstract
The present invention relates to a process for the application of a reflecting coating on a metallic surface such as sheet metal, whereby there is applied to the unpolished metallic surface, a layer of a pulverulent dressing; said layer is subjected to a heat treatment with a view to fixing it on the metallic surface and creating a surface having undulations coexisting with micro-fissures; the layer thus fixed is smoothed by the deposit of a layer of varnish intended to fill in the micro-fissures while conserving said undulations, and the surface thus obtained is then subjected to a conventional metallization operation. The invention finds particular application to the production of reflectors having a high power of reflection.
