Cataphoresis E-coat
Cataphoresis is a pivotal and a longest time used technology of the surface treatment in the LAKUM-KTL, a.s. It involves deposition of paint by an electro-phoresic method, whereby the painted product becomes a cathode in the direct current anolyte (water solution of the epoxy paint) and thus attracts the colour cations. It represents one of the most progressive fabrication technologies of depositing basic paints, delivering a high degree of protection against a corrosion of metals. The cataphoresic method of paint deposition is considered to belong among the most contemporary technologies of metal products surface treatments. Currently, in the whole field of fabrication areas it does not have a comparable competition. The most important share in development of the Cataphoresis technology has the automotive industry, as the anticorrosion protection of body components and other parts, becomes a center point of interest for all manufacturers. High quality of the surface treatment, together with the economic and ecological advantages earmarked this technology for utilization also in other fields of machine industries as well as consumers goods industry.
CATAPHORESIS ADVANTAGES
- It is possible to deposit paint over any electrically conductive material, including complex shapes, body cavities and such
- It is a suitable anticorrosion basic surface treatment for subsequent powder paint deposition techniques
- It is also suitable as a base paint layer for subsequent varnishing (acrylate, water soluble lacquers, etc.)
- It is also suitable as a final anticorrosion surface treatment
- It offers a possibility to paint hot dipped surfaces, zinc galvanized materials and aluminum.

TECHNICAL VARNISH PROPERTIES
POWERCRON 6200 is the most recent enhancement of the 6th generation cationic epoxy electrocoat without the use of heavy metals . It is used to protect automotive parts, steel wheel disc and other accessories with different thickness of the layer. Chemicals used to primary preparation of surfaces are supplied by the firm Henkel. Final coat of cataphoretic paint is conceived for the use of the automotive industries; it satisfies required specifications form manufacturers, such as (for example): VW 137 50 x634, DBL 7391 AA 54, GS 90011 LASW 3 and other.
