Machine components made of metal are exposed to harsh conditions like extreme temperatures, corrosive environments and pH. Protecting such metal components therefore becomes essential for the smooth operation of the machine. Surface finishing by metal treatment chemicals aids in reducing friction which in turn reduces the abrasion caused when two or more parts come in contact with each other. The application of surface treatment chemical increases physical properties like hardness, wear resistance and chemical resistance. Metal treatment chemicals play a vital role of improving adhesion and surface wetting when coatings or paints are to applied to the metal surface. Metal treatment chemicals are not limited to metals and alloys but also utilized for treatment of printed circuit boards, which are composed of plastic and metal parts. Metal profiles prefer surface treatments such as electroplating, which involves formation of metallic coating on surface and anodic oxidation for light metals such as titanium and aluminium. Additives and sealants are also used to ensure efficient application of other chemicals.
