Abstract
Copper or copper alloy articles are coated with silicones by first treating the articles with reducing substances and then coating with the silicone in a non-oxidizing atmosphere. Copper wire is treated by first reducing in an atmosphere of hydrogen the copper oxides which cover the wire and then applying silicone varnish while still in a hydrogen atmosphere and without the wire having been exposed to any oxidising action. The reducing action may be carried out in the hydrogen atmosphere at a temperature above 250 DEG C. the coating applied and then the article heated to polymerize the composition while in the hydrogen atmosphere.
