HTP-100 enhances the use of commercial refractories, leading to significant savings by:

  • Enabling higher porosity IFBs in corrosive environments
  • Increasing thermal efficiency of refractories through high emissivity
  • Simplifying refractory repair and reducing downtime

The images shown left are from an experiment to demonstrate how Cerablak® HTP-100 protects refractory bricks from molten salt exposure (sodium and potassium).

The SEM and EDS images show that the salts were confined to the surface. The coating also demonstrated excellent mass stability, with coated samples gaining only 33% of their mass during immersion, compared to uncoated samples that disintegrated.

While there are many high emissivity ceramic coatings in the market, maintaining high emissivity over prolonged service times has limited the broad use of high emissivity coatings.

HTP-100 retains its emissivity characteristics even after 800+ hours in service above 1470 °F, increasing efficiency without needing constant maintenance or replacement.
