Cataphoresis – high-tech dipping coating method

Cataphoresis or electrophoretic coating in general is the most high-tech, economical and highly ecological way of coating. It is used as a surface treatment of metal products, especially for steel, galvanized and aluminium parts. We provide complete industrial lines for:

• Cataphoretic coating;
• Anaphoretic coating;
• Rebuilding of anaphoretic lines to cataphoretic lines.

Cataphoresis – Why choose cataphoretic coating of metals

Currently, a cataphoretic coating is technologically the most advanced method of anticorrosive surface treatment for metal products.

Cataphoretic coating is mainly used as a base layer, followed by other surface treatments (dipping or powder coating). However, it is also often used as a final, single-layer, painting. The use of cataphoretic coating guarantees a significant increase in the corrosion resistance and utility properties of the products, which are significantly increasing its application on the market.

The benefits of cataphoresis

• High corrosion resistance even at low paint thickness;
• Very good retractability - cavity protection;
• Uniform coating thickness over the entire surface including hard to reach places;
• No drops or irregularities in the applied paint layer;
• Constant reproducibility;
• Low demands on operating personnel – automatic coating process;
• High paint yield over 99% – economical closed circuit;
• Fast coating process (180–240 sec.);
• Eco-friendly operation – minimum emissions, wastewater, solid waste and minimum solvent content;
• Safety – no special safety measures required.

Customized cataphoresis lines from MEGA–TEC

Industrial lines for cataphoretic coating are designed according to customer requirements and needs. The lines are constructed depending on the type of assortment and with regard to the batch production of coated parts. The final concept of cataphoresis is always chosen according to the economic advantage for the customer.

The pressure on corrosion resistance combined with the advantages of the highly economical surface treatment process together with the environmentally friendly operation has made cataphoretic coating an important technology, especially for the automotive industry. However, this technology soon spread to other fields of engineering and consumer industry.
