Wetting Agents in Metal Treatment: A NEW SERIES OF PRODUCTS

Almost every metal article, at one or more stages during its progress from the rough casting or forging to the finished product, undergoes a wet process. Such a process, which may be acid pickling, alkaline degreasing or derusting, electroplating, phosphating or rinsing, or may form part of a mechanical treatment such as drawing or cutting, involves the contact of an aqueous solution with a metal surface and some chemical or physical action there: chemical dissolution of scale, physical removal of grease, deposition of a metal or a compound etc.
