PROCEDE D'OBTENTION D'UN REVETEMENT BRILLANT EN CUIVRE SUR UNE SURFACE DE VERRE ET OBJETS EN VERRE TRAITES CONFORMEMENT AUDIT PROCEDE

摘要

A process for forming a reflecting copper coating on a face of a glass substrate, consisting in activating the glass face in a 0.0005 to 0.007% by weight aqueous solution of SnCl2.2H2O and a 0.005 to 0.15% by weight aqueous solution of AgNO3, chemically coating the activated face of the glass substrate with copper for 3 to 15 minutes in a coppering solution preheated to 30 DEG to 65 DEG C., followed by stabilizing the coated face of the glass substrate with an aqueous solution of a stabilizer and drying thereof.
