SIBOR® is a patented protective coating for molybdenum in oxidising atmospheres up to 1600°C and it was developed by PLANSEE especially for applications in the glass industry. Under oxidation, the very hard and dense coating generates a diffusion barrier against the base material and creates a SiO₂ seal where it is exposed to air.

SIBOR® provides optimal oxidation protection to enable molybdenum with its excellent thermo-mechanical and corrosion resistant properties in glass melts to be used during the up-tempering phase in air.

Advantages:

• High long-term stability
• Quick dissolution in the glass
• No glass discolouration

Applications:

• Oxidation protection for rod and plate glass melting
• Oxidation protection for tank reinforcements for
  • Throats
  • Doghouses
  • Bubblers und crosswalls
  • Floor drains
  • Glass flow pipes and glass delivery systems
  • Electrode holders
