Abstract
To prevent their corrosion, articles of copper or copper alloy are coated with a mixture of a methyl phenyl siloxane resin and a polymeric methacrylate resin, which mixture has been treated with boric acid. Suitable polysiloxane resins are described in Specifications 542,655, 548,911 and 572,230. The mixed resins dissolved in a hydrocarbon, e.g. toluene, may be refluxed with boric acid, or readily hydrolysable borates, e.g. ethyl, propyl or butyl borate may be employed. Suitable resin mixtures contain 15-35 per cent by weight of methyl methacrylate resin based on the weight of methyl phenyl polysiloxane resin. Felted asbestos tapes may be impregnated with the treated resin mixtures and its surface afterwards dusted with boric acid. The treated compositions may also be applied as films to copper conductors or be used as impregnants for glass or asbestos sheet insulation. p The coating according to the invention may be applied over a layer of other insulation, e.g. cellulose acetate directly in contact with the copper conductor. A final coating of glass braid impregnated with the resin mixture may also be applied (see Group XXXVI). Specifications 549,081 and 552,640 also are referred to. The Specification as open to inspection under Sect. 91 includes the use of a coating comprising only an organo-polysiloxane resin which has been treated with boric acid. This subject-matter does not appear in the Specification as accepted.
