Before applying powder-coating it is necessary to prepare the surface of the material which is done by degreasing and zinc-phosphating.

The KTL is a type of dip-painting procedure, that utilises electrochemical processes for extracting paint. The physics principle that serves as a basis of this process is that objects of opposite charge mutually attract each other, so this way a very strong adhesion can be achieved.
By this cathodic dip-painting the resulting layer of painting is very evenly spread on metal surfaces and in micro-cavities and scores very high in durabiliy tests.
By applying this method together with the already existing surface treatment procedures we can guarantee a very reliable undercoat before the actual powder-coating treatment.

In order to achive a very durable surface coating it is important to remove all dirt, oils and other residues from the material. Degreasing in liquid (phosphating) gives an optimal surface and results in a high adhesion between the material and the powdered lacquer, so today, it is an indispensable part of the powder-coating process.

Preparing the surface before the actual painting with environmentally friendly chemical agents.
The zinc-phosphate layer exhibits excellent insulation properties, the resulting crystalline-rich coating is 5 to 6 times smoother than the untreated surface. The process results in a matte, dark grey finish.

The oxidation of primarily unalloyed or low-alloy tool steels in hot alkaline bath, containing natrium-nitrate and/or natrium nitrit. The resulting magnetite layer sticks excellently to the base metal, it is relatively hard and durable. The corrosion resistance can be increased with oil treatment. Depending of the material, its machining, the chosen oxidation liquid, the achieved surface can be bluish, brownish or black/grey.
The most widely used technology in galvanising shops. After pretreatment (cleaning, degreasing) the highly purified zinc in the galvanisation liquid is deposited onto the material by the aid of electricity. Depending on the type of liquid used in the passivation the finish can be the typical yellow or blue.
This process is done by an electrochemical procedure which is used not only for the protection of metal surfaces but also for the passivation of galvanic coatings. It is a frequently used method for corrosion protection. The various chromate coatings are differentiated by their colour: transparent, blue, yellow, olive green, black. The darker the colour of the coating the more corrosion resistant the it is, though, the spot weldability and solderability of the material decreases accordingly.
