Oxsilan®

The Oxsilan® technology is an eco-friendly and multi-metal pretreatment process. The innovative technology is used likewise for the appliance industry as well as pretreatment for premium car bodies.

The more stringent environmental legislation as well as the ever more varied metal combinations in applications are giving traditional phosphating processes a hard time. With the Oxsilan® technology, a state-of-the-art alternative is now available which is used successfully in a variety of industries for several years. In terms of quality, it is comparable to the zinc phosphating process, and with a view to its technical and economic feasibility, the new technology is clearly advanced:

  • lower process costs
  • higher productivity
  • multi-metal capability
  • eco-friendly: lower risk for safety, health and environment
  • excellent quality

 

Broad portfolio for diversified applications:

The Oxsilan® technology has been formulated to provide a range of products that are compatible with all conventional wet and powder coating processes and can be used:

  • as replacement of zinc- and iron-phosphating
  • prior to painting
  • bare corrosion protection
  • passivation

 

Oxsilan® technology

The Oxsilan® process is based on silanes that form aqueous solutions, through hydrolysis and condensation, polysiloxanes. During the coating process, the reactive silanol groups can be chemically bonded to the metal as well as to the paint coating. Heat treatment, e.g. following cathodic electropainting (CEP), further cross-links the polysiloxanes. This creates layers in the range of 100 nm. In combination with many paint systems, this is already sufficient to achieve the same degree of corrosion protection as with the ten times thicker zinc-phosphating layers, thereby reducing materials consumption and pre-treatment times and increasing productivity: improvements of 30 and 65% have been realized in practical applications.
