Metal Treatment
The preparation is commonly referred to as coatings pretreatment. This usually involves the creation of a physical barrier that will help in the protection of metal against a corrosive environment.
Metal Treatment that modify and clean the surface of several metallic and organic substrates improving the performance of the finished articles and enhancing their shelf life. This includes increased corrosion resistance, improved lubrication properties and enhanced effectiveness of metal working fluid concentrates.
ELECTRO-PLATING
Electro-plating involves the electrochemical application of a thin metal sheet onto the surface of steel or non-ferrous metal. The material will go through various pre-treatment stages depending on the surface condition in order to produce a chemically pure surface. The levels of corrosion protection to be classified according to the component’s level of exposure can be determined based on the corresponding specifications of coat thicknesses.
ANODIZING
Anodizing or electrolytic oxidation of aluminium is a proven corrosion protection process for aluminium components.In contrast to electro-plating whereby the separation of a metal takes place electronically on a substrate, with anodizing, the base material itself is converted into an oxide layer.
PHOSPHATING
Phosphating is a chemical process for treating the surface of steel whereby metal-phosphate layers that are hardly soluble are formed on the base material. The layers created are porous, absorbent and are suitable without further treatment as a conversion layer for subsequent powder coating. They are also suitable as temporary corrosion protection if subsequently treated with oil, water or passivation.
- Temporary corrosion protection for steel, which should be stored for a limited period before further treatment
- Good promotion of adhesion for subsequent color coating
- Improving the sliding properties when cold forming steel
- Electrical insulation
- Decorative appearance
- Mechanical resilience
