The processing of the robust Chrome System basically corresponds to the usual procedure for spray metallisation: First, a transparent primer (basecoat) is applied to the surfaces to be metallised. It is extremely important that the parts are clean and free of grease on the surface. The coating should be applied in rooms that are as dust-free as possible. An important point here is the attachment of the parts to be finished to holding devices. The type of holding device to be used for the respective part depends primarily on the size and shape of the objects. The primer provides a flawlessly smooth substrate for the subsequent metal layer and is characterised by good wettability and water absorption. The primer (basecod) must be dried very carefully – either for 60 to 150 minutes in a dryer at 60 to 90 degrees or for 48 to 60 hours at room temperature.

The next steps follow immediately after each other. First, a so-called activation solution is sprayed onto the parts to be finished. The activation process continues until a closed film of water forms on the surface, which is then made receptive for subsequent chemical metal deposition. Immediately after activation, the parts are washed with ionised water.

This thoroughly washes out the excess activation solution. Then, metallisation is carried out using a special two-component gun. Silver salt is sprayed from one nozzle of the gun and a reducing solution from the other. The two jets mix outside the gun at a specific angle. When the two jets meet, the chemical reaction begins and, as a result, metal precipitation.

The metal film builds up extremely evenly and quickly. The spraying time is 30 to 60 seconds. Afterwards, the objects are thoroughly rinsed again with water to remove any chemical residues.
