CDP (Cataphoretic Dip Painting)

Brief technical description:

• Cataphoretic dip painting is an electrochemical paint deposit process. Tools are immersed in an aqueous paint that conducts electricity, and a charge field is applied. The paint coating is then fired at approximately 200 °C. A highly uniform, closed organic paint surface is formed.

Advantages:

• Good corrosion resistance
• Corrosion protection, also for hollow spaces and undercuts
• Even coating thicknesses

Please note:

• The so-called duplex systems are formed in combination with a Zn or Zn/Ni alloy substratum. These are two-step systems consisting of an organic KTL top coat and a substratum consisting of a Zn, Zn/Fe or Zn/Ni coat. This system offers the highest degree of corrosion protection (up to 1000 h of protection against base metal corrosion during a salt spray test according to DIN 50021 SS), while at the same time offering good resistance against thermal and mechanical loads.

Fields of application:

• Automotive and supplier industry (for components that must be highly corrosion-resistant).
• Building machinery
• Consumer industry
