The PYROSIL technique is a process which is used to produce SiOx layers in order to modify surfaces. This is accomplished by using Combustion-Chemical Vapour Deposition, a cost saving atmospheric pressure technique. As precursors both liquid and gaseous compounds can be used.
The precursors are pyrolysed by a flame, which also serves as a heating source for the substrate allowing both in-line and off-line integration into an existing process.
The SiOx coatings have the potential for several different applications e.g. improved long time stability and mechanical stability of hydrophobic coatings on glass, improved adhesion of organic coatings (such as powder coatings, adhesives), antireflection and therefore transmission improving properties and so on.
