• HPC™ Coating Specs and Uses


    • Reduction of external temperature of hot surfaces as an aid to worker safety
    • Reduction of heat loss for energy savings
    • Stops condensation
    • Stops CUI (corrosion under insulation)


    Although HPC™ Coating can be applied by non-professionals, SPI recommends using a SPI certified applicator.


    • Surface must be clean and completely dry, with no loose debris or particles, rust, dirt, oil, films or residues of any kind. HPC™ Coating will cover previous coatings, provided they are fully adhered to the surface and no gloss surface
    • Mechanically stir, as formula will tighten and give the appearance of cake or putty. Stirring loosens and relaxes the consistency.

    Application methods

    • Graco Texspray RTX 1500 using 2mm nozzle
    • Over hot surfaces apply a 50 wet mil (1.25 mm) primer coat to allow a steaming-off and cooling of surface to avoid bubbles, and then increase thickness with additional coats as needed

    Applied rate

    • 80 sq. ft./gal. (7.4 sq.m./gal.) as primer
    • 2.4 - 9.6 sq. ft./gal. (0.22 – 0.9 sq.m./gal.) with build coats (125 mils - 500 mils dry per coat)

    Film thickness

    • 50 mil wet (1.25 mm) as primer
    • 125 - 800 mils dry (3 – 20 mm) with build coats depending on need to control different ranges of heat
    • Fire Control System 800 mils - 1600 mils (20 mm - 40 mm) as the primer before Omega Fire™ top coat.

    Dry times

    • 10 minutes as primer over hot surface, then increase thickness as needed.
    • 24 hours to set


    • Do not use for exterior applications unless top coated with Super Therm® for long term durabilit


    • Do not use for underwater applications.
    • HPC™ Coating is light yellow in color and rough in texture
    • Not recommended as the only fire protection material to be used in residential or industrial construction
    • Do not use as floor coating
    • Not UV protected. For external use overcoat with Super Therm®
  • HPC™ Frequently Asked Questions

    Is HPC™ Coating a reflector?

    No. HPC™ Coating uses only non-conductive ceramics. HPC™ Coating is designed not to absorb, but to catch and hold heat on the surface.

    When should I use HPC™ Coating instead of Super Therm®?

    HPC™ Coating is designed to prevent conductive heat transfer, while Super Therm® works on radiational and convective heat transfer. Use HPC™ Coating to reduce heat loss from conduction in conditions with high temperatures.

    HPC™ Coating catches and holds heat "onto" a surface. Super Therm® repels heat off of or away from a surface and does not allow the surface to load heat from the heat source.

    What is the best topcoat for HPC™ Coating?

    HPC™ Coating must be sealed with Super Therm® before any solvent-based topcoat can be used. For exterior use, overcoat with Super Therm®. For use in a chemical environment, overcoat with Super Therm® and with either Rust Grip® or Enamo Grip (if color topcoat is desired).
