Abstract

548,033. Oxide coatings. SOC. OF CHEMICAL INDUSTRY IN BASLE. Jan. 30, 1942, No. 1303. Convention date, Jan. 31, 1941. [Class 41] Dyed or undyed oxide coatings on aluminium or alloys thereof are sealed by treatment in a hot aqueous bath containing one of the cation active assistants, especially those containing a long aliphatic or cycloaliphatic radical, such as the quaternary ammonium compounds from dimethyl sulphate and 4-dimethylamino-1-stearylaminobenzene, mono-oleylated asymmetrical dimethylethylenediamine, and 4-dimethylamino-1-stearyl-aminobenzene. Specifications 455,412 and 491,618 are referred to.
