Surface pretreatment
The treatment of surfaces for influencing the adhesion of glues, coatings or printing media by means of combustion is a method established for years in numerous industrial fields.
A further significant improvement of the adhesion can be achieved by deposition of a reactive silicate layer, produced by flame pyrolysis. Through Combustion of a silane additive component in a combustion-gas atmosphere, are produced very dense and adhering silicate layers with high surface energy to materials, such as metals, glass, ceramics and plastics.
The surface pretreatment ensures the:
Generation of a high-energy silicate layer (layer thickness max. 40 nm) on the material surfaces via flame pyrolysis (surface silicate coating)
- Application of an adhesion promoter, suited to the adhesive, the coating or to the printed medium
- Improvement of the wettability of the surface
In combination to adhesion promoters with the corresponding functionality, the layers ensure the basis for long-term-, water- and solvent-stable adhesions, coatings and prints. Further applications of this technology are the temporary corrosion protection as well as the production of diffusion barrier layers.
