Grupo Kataforesis, specialists in anti-corrosion coatings for industryCathodic electrodeposition or cataphoresis is an immersion painting process, fully automated and based on the displacement of charged particles within an electric field (paint) towards the pole of opposite sign (metal part to be painted). The main objective of the treatment is the protection of surfaces against corrosion, a field in which its properties make it the ideal treatment for this purpose. This treatment allows the painting of areas that are difficult to access such as hollow areas, pipes, etc.
efore applying the paint, the parts go through a surface preparation process consisting of degreasing, tricationic phosphating and different washes. After the application of the paint, the part is subjected to temperature to achieve its polymerization.
More and more industries are selecting cataphoresis as a coating type due to its excellent finish quality, high productivity, reasonable costs and high efficiency. Cataphoresis can be used as a final finish or as an excellent base for other types of final finishes. Easily conforms to original configurations while maintaining design tolerances on parts
From rolled, galvanized or stainless steels, to iron or aluminum forgings, thanks to the fact that easily adjusts to original configurations, maintaining the design tolerances in the parts.
The proximity to the European border makes our companies a good solution to save transportation costs.
Cataphoresis and automotive
Cataphoresis is the electrochemical process used in the anti-corrosion treatment of sheet metal bodies and/or automotive parts. Also known as phosphating, the part is immersed in a liquid consisting of phosphorus and subjected to a positive stress.
Negative tension is applied to the workpiece, which attracts the phosphor particles uniformly accessing all corners.
Cataphoresis benefits
Why choose cataphoresis?
Currently, cataphoresis coating is the most advanced method of coating that
exists for the anticorrosive treatment of metal surfaces.
Cataphoresis is usually used as a base coating, to be used at the end of the coating
for subsequent use of other surface treatments.
However, it’s also commonly used as a single coat treatment. The use of cataphoresis guarantees a significant increase
in corrosion resistance, which allows a wide range of sectors in which this technology can be used.
