HPC®-HT PRIMER is a single-component resin, water-based coating using specific ceramic fiber loads for application directly over surfaces 200°C (392° F) and up to 600° C (1112° F). It was designed to provide the initial adhesion over extremely hot surfaces before the heavier-loaded HT is applied.

HPC®-HT PRIMER offers a ‘green’, nonflammable, non-toxic formula for high-heat surface priming. HPC®-HT is easily applied, and can be applied direct to metal, and other high-temperature surfaces.

NOTE: Can be applied over ambient but takes a day to dry.


  • As the high-temp primer coat for surfaces greater than 250°C, over hot pipes, tanks, and valves
  • Applied when a hot system cannot be shut down.
  • NOTE: A respirator should be worn while mixing and applying the HPC®-HT PRIMER.
