The first step of the coating is in principle the pretreatment. This is substrate-specific and has the goal, in addition to the cleaning, to increase the surface energy and to apply an adhesion-mediating layer (mediator).
The coating process is based on the sol / gel process for the preparation of inorganic or hybrid-polymer materials from colloidal dispersions, the so-called solenes. Solenes are produced in our laboratories that produce or significantly improve defined properties in the coating, while several properties can be combined within a coating system at the same time.
Existing application technologies are immersion and spray coating in automated systems and are adapted to the respective requirements and general conditions. As a rule, extremely thin layers are applied, which typically range from 10 nm to 3 μm. For special applications, hybrid-polymer sol / gel coatings are sprayed to a thickness of 100 μm.
In order to ensure a high adhesive strength of the coating, a thermal aftertreatment, the so-called tempering, is required.
Depending on the substrate material, the coated substrates are heated in the temperature range from 100 to 900 degrees Celsius over a defined period of time. The annealing process results in a compact, glassy sol / gel layer, which forms a firm bond to the substrate surface.
Tempering is carried out as standard in radiant or convection ovens.
In addition to the possibility of visual inspection, we have a wide range of analysis methods from the area of adhesion, layer stability and temperature stability tests, as well as optical test methods, such as transmission, reflection and light measurement techniques, for the final product exit control.
