An electroless gold plating process in which the workpiece to be plated has a nickel coating, the process resulting in formation of a nickel/gold alloy that exhibits the majority of the physical characteristics exhibited by pure gold plating.

Gold plating process and product produced thereby

A novel encapsulating material and method of making said material is described wherein an organopolysiloxane polymer is mixed with a polydimethyl siloxane fluid diluent, a filler of hollow glass beads and a controlled amount of sodium in the form of sodium borate. A methyl hydrogen siloxane catalyst is added to the mixture and the material cured; the total amount of sodium present in the mixture and catalyst is maintained at approximately 180 ppm.
