| abstract | 503,034. Metallizing. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE SAINT-COBAIN, CHAUNY, ET CIREY. Oct. 20, 1937, No. 28580. Convention date, Oct. 21, 1936. [Class 82 (ii)] A wet method of metallizing surfaces is characterized in that the surface, first brought into condition to adsorb, a molecular layer of metallic ions, then receives this layer by contact with an alkaline solution of a metallic salt or of an auric, platinic or argentic hydroxide, free from any reducing agent, after which the surface is freed from any excess of ions, and is then metallized by contact with a solution containing a salt of the metal to be deposited. 'Any metal of positive electrode potential such as mercury, bismuth, gold, silver, copper, antimony, rhodium, palladium, osmium, platinum, &c. may be deposited upon surfaces such as polished metals, glass, ceramic materials, mica, cellulose or its derivatives, polymerized resins, varnishes, gums, rubber, ebonite, or organic plastic material having a base of urea, acetals, formol and phenol compounds and synthetic resins. In the case of metallic surfaces, glass, ceramics or mica the first treatment is a cleansing, e.g. by acid followed by rinsing with water. In the case of an organic material, this first treatment is by means of a solvent such as zinc chloride, cuproammonium solutions, or an alcohol, aldehyde, ketone, or organic acid. When the second treatment is by means of an auric &c. hydroxide this treatment is preferably preceded by a washing with stannous chloride together with a rinsing with water. In gilding a copper surface the cleaned surface is submerged in stannous chloride, washed, treated with silver hydroxide solution, washed and finally left in a bath containing sodium aurate, glucose, levulose, and sodium tartrate. In antimonizing a glass surface, the surface is cleaned, immersed in stannous chloride, washed, treated with auric hydroxide solution, washed, and finally immersed in the metallization solution containing antimony trichloride, tartaric acid, sodium hydroxide, ammonium hydroxide, formaldehyde hydrosulphite, ammonium ferrous sulphate, formaldehyde and water. In silvering a film of cellulose acetate, the film is treated with quinone solution, washed, immersed in cuproammonium solution, washed, immersed in a solution of stannous chloride with or without phenol, washed, treated with auric hydroxide solution, washed and then metallized, for example with ammoniacal silver hydroxide and glucose. If the film is to be coppered the metallizing solution contains tartaric acid, copper sulphate, ammo nia, formaldehyde hydrosulphite, iron ammo- .nium sulphate, formaldehyde and water. The metallization solution may be applied a second time. |
