With high temperature too high resistance
To cure the coating layer, the organic molecular groups must be cross-linked with each other, integrating the inorganic structural elements. This process takes place very intensively at higher temperatures and a very dense three-dimensional network is formed, resulting in a thermoset scratch-resistant layer with high mechanical and chemical resistance.
By curing in an oven, even parts with complicated surface shapes can be cured. However, the thermal load on the parts is quite high (120 °C to 180 °C) and the curing times are relatively long, which is why thermal curing is primarily used for coated glass or metal objects.
However, components made of plastic with the corresponding temperature resistance can also be cured in the oven or by infrared radiation.
