    Abstract: An article comprising a metal substrate in the form of a pipe or a container, said substrate being coated with a hardened epoxy resin composition formed from (A) a solid epoxy resin based on epichlorohydrin and a component selected from the group consisting of (a) 4,4'-diphenylolpropane, (b) 4,4'-diphenylolmethane and (c) a combination of (a) and (b), (B) from 1 to 12% by weight based on the epoxy resin of at least one hardener for said epoxy resin selected from the group consisting of (d) compounds of formula ##STR1## wherein R is hydrogen or an alkyl group of 1 to 6 carbon atoms or an aromatic hydrocarbon residue with 6 to 10 carbon atoms, (e) compounds of formula ##STR2## wherein R is hydrogen or an alkyl group having 1 to 6 carbon atoms or an aromatic hydrocarbon residue with 6 to 10 carbon atoms and (f) an adduct of any one of compounds (d) and (e) to an epoxy resin with an epoxy equivalent weight of from 50 to 2000, (C) a flow agent, (D) a thixotropic agent and a process of coating such metal substrate by means of heating said substrate to a temperature above the melting temperature of the epoxy resin component of an epoxy resin coating composition and sufficient to cure the said epoxy resin and powder-coating the said epoxy resin composition onto the hot surface of the substrate to provide a substantially uniform coating thereon by immediate hardening without any further processing step by means of the heat capacity of the hot substrate.

    Abstract: The present invention relates to an apparatus for the partial surface coating of objects, such as electrical components, moving past an electrostatic coating station where they are coated with electrified particles of coating material. According to the invention the portion or portions of the components which are not to be coated, e.g. the connecting wires of electrical components, are maintained in a zone of pneumatic over-pressure during their passage through the coating station, whereby such portions do not become coated.

    Abstract: A METHOD FOR APPLYING A DECORATIVE, METALLIC FLAKE FINISH TO AN ARTICLE. THE METHOD COMPRISES THE STEPS OF: (1) HEATING THE ARTICLE TO ABOVE THE MELTING TEMPERATURE OF A PRESELECTED TRANSPARENT THERMOPLASTIC RESIN; (2) WHILE THE ARTICLE IS HOT, COATING THE ARTICLE WITH A MIXTURE OF ALUMINUM FOIL FLAKES AND THE THERMOPLASTIC RESIN IN POWDER FORM; (3) REHEATING THE ARTICLE UNTIL THE POWDERED RESIN IS FUSED; (4) WHILE THE ARTICLE IS HOT, ELECTROSTATICALLY COATING THE ARTICLE WITH A SECOND LAYER OF A POWDERED, TRANSPARENT THERMOPLASTIC RESIN; AND (5) REHEATING THE ARTICLE TO FUSE THE SECOND POWDERED RESIN COATING INTO A SMOOTH LAYER. A PRIMER COATING MAY BE APPLIED TO THE ARTICLE TO INCREASE ADHESION BETWEEN THE ARTICLE AND THE DECORATIVE FINISH. CELLULOSE ACETATE BUTYRATE IS A PREFERRED THERMOPLASTIC RESIN. THE PRIME-COATING MAY BE APPLIED EITHER IN LIQUID FORM BY SPRAYING, OR IN POWDERED FORM BY MEANS OF EITHER A FLUIDIZED BED OR AN ELECTROSTATIC

    SPRAYER. THE POWDER COATING MAY BE APPLIED BY A FLUIDIZED BED.
