Tri-valent Chrome Plating Anodes

In recent years, health and environmental regulations have become more stringent regarding the use of hexavalent chrome plating baths. As a result, platers are being forced to convert to tri-valent chrome baths whenever possible.

GreenChrome™ is a family of coating developed in close conjunction with the most important chemical bath providers to match the characteristics of the bath improving both uniformity of the deposition and the brightness of the deposit. GreenChrome™ anodes are being recognized as the best suited solution for almost all the tri-valent plating baths as they have long life and are specifically designed to prevent the destruction of the organic additives in the plating bath chemistries. 

Electrophoresys

Electrophoretic deposition (EPD) is a term for a broad range of industrial processes which includes electrocoating, electrophoretic coating, or electrophoretic painting. A characteristic feature of this process is that colloidal particles suspended in a liquid medium migrate under the influence of an electric field (electrophoresis) and are deposited onto an electrode. De Nora’ new technology prevents problems affecting Electrophoretic painting like:

• Gas forming (Hydrogen gas at the cathode, and oxygen gas at the anode)
• Variable resistance

De Nora has developed special anodes and cathodes for industrial processes that apply coatings to metal fabricated products such as automobile bodies and parts coating, tractors and heavy equipment, electrical switch gear, appliances, metal furniture, beverage containers, fasteners, and many other industrial products. This process has a number of technical advantages which make it widely used:

• The process applies coatings which have a very uniform coating thickness
• Complex fabricated objects can easily be coated, both inside cavities as well as on the outside surfaces.
• Less human labor and material costs than other coating processes.
• Modern electrophoretic paint products are environmentally friendly
