Component Identification:

Cataphoretic Immersion Priming (CIP) is the basis for permanent corrosion protection, in conjunction with filler and top coat.
With cataphoretic immersion priming the phosphatized bodies and detachable body parts are lowered into an immersion bath with water-thinnable primer. By immersing the body at a special set angle (and due to the so-called hole pattern in the bodies) air bubbles in cavities are avoided and an optimum coating of the cavity is ensured. An electric field is produced between the body and the immersion bath. The positively charged paint particles (anode) deposit themselves on the negatively charged body (cathode).

The separation voltage and coating period (dwell time in dip tank) are selected so that there is an even film of paint on the body and in its cavities. Once the body is moved out of the bath, the loosely adhering primer material is rinsed off with ultrafiltrate and deionized water. The special advantage of cataphoretic immersion priming is the even coating, even in inaccessible areas such as cavities, corners and edges.
With this process, solvents which are hazardous to health and harmful to the environment can largely be dispensed with.
