Abstract
A method of preparation of fiberglass filaments for subsequent coating with metal wherein the fiberglass filaments first are immersed in a wetter solution containing alcohol, a detergent, and an ethylene oxide and propylene oxide copolymer surfactant. Following this treatment the filaments may be treated with conventional palladium chloride or tin chloride activators, followed by treatment with an acid accelerator and then autocatalytically coated with metals such as copper, gold, palladium, cobalt, nickel, and nickel alloys of phosphorus, boron, or tungsten. A second electroplating or immersion plating step may be included where the metal-coated filaments are electroplated or immersion plated with either the same metal, or a different metal taken from the group consisting of nickel, silver, zinc, cadmium, platinum, iron, cobalt, chromium, tin, lead, rhodium, ruthenium, or iridium. The filaments are rinsed with water following immersion in the wetter solution and after each plating step and then finally are rinsed with alcohol and dried.
