Cataphoresis is one of the most modern and the best methods to apply paints in and steel, coated steel, e.g. casting, forgings, welded, welded, aluminum, iron and other conductive alloys electricity. It is used to protect objects that require coating of high corrosion resistance. These coatings are also characterized by high aesthetic value. 

Cataphoretic painting process can include a group of clean technologies, friendly environment, as it emits the smallest of all the ways the amount of paint pollution. Cataphoresis can also be an excellent primer for other coatings like powder or spray.

Cataphoretic paint workshop in the Department of Mechanical Engineering ,, SKRAW-MET "is adapted to painting of metal products with maximum dimensions of 2600mm x 1400mm x 300mm.
The maximum weight of the component – 150 kg. 

Items for line painting are already thoroughly blasted to remove corrosion and weld spatter.

The line operates in the automatic system and implemented on technological operations:

In terms of surface preparation
- Alkaline degreasing bath – hot,
- rinsing in water the first network,
- rinsing in demineralized water, second with fresh     water spray demineralized on the ascent of the tub     hanger,
- nanoceramic bath (zirconium), 
- rinsing in demineralized water first,
- rinsing in demineralised water, the second – the       fresh  demineralized water spray on the ascent of     the tub hanger,

In terms of painting
- electrocoated in the paint bath black
- rinsing ultrafiltrate ,,dirty "
- rinsing ultrafiltrate ,,pure "fresh spray of the       ultrafilter at the emergent tag of the tub.

After painting the paint film is dried at 180 deg. C for 30 min.

In the process of surface preparation applied degreasing agents and nanoceramics  of HENKEL company which guarantees high quality.

The painting applied the paints of the companies “BASF"

Cataphoretic painting in the surface preparation provides:

- the best possible adhesion to the substrate and into   the next applied layer,
- the highest penetration in the paint hairline gap in   the most inaccessible places, even between the spot   welded sheet metal,
- uniform and controlled film thickness.

The standard thickness of the coating is approx. 25 microns,  with appropriate adjustment coating parameters we can obtain a coating of about 40-50 microns.

The above-mentioned production process will provide optimal corrosion resistance of the coating (nanoceramics and cataphoresis) from 500 to 720 h. of a standard salt spray test which in conjunction with accordingly adapted applied next paint coating, can provide resistance of more than 1000 hours.         The corrosion resistance of 500 hours meets the requirements for parts parts in the automotive industry.

Cataphoresis paint workshop does not create chemical, fire and explosive risks. 
There are only waste water washing in preparation surface, requiring adequate purification
