• In a joint research project with the Institute for Materials Science at TU Dresden, HVOF and suspension sprayed insulation layers are developed.
  
  
• These layers are denser than conventional thermal sprayed insulation layers. They show a higher insulating capability at lower layer thickness.
  
  
• Due to their high thermal conductivity these coatings can be used in circuit boards for power electronics, which are more and more desired in the automotive industry.
  
  
• Project Sponsor: BMWi, Zentrales Innovationsprogramm Mittelstand ZIM; Code: KF3197501

Further fields of application for dense suspension sprayed insulation coatings:

• Heating conductor coatings for stoves, plastic injection molding and many other areas
  
  
• Non sealed insulation coatings approved for medical products
