HPC™-HT ia a two-part hybrid silicone/solvent resin. (Part B is flammable and Part A is water-based). The coating is using specific ceramic compound loads for application directly over surfaces minimum temps of 250°C (482°F) and up to 600°C (1112°F). It was designed to block and hold the interior temperature on the surface and reduce heat transfer loss to ambient.

After Part A and Part B are blended together, HPC™-HT Coating offers a ‘green’, nonflammable, non-toxic formula for high-heat surface applications. HPC™-HT is easily applied, and can be applied direct to metal, concrete and other high-temperature surfaces.

HPC™ HT-PRIMER is applied fist for best adhesion.
If the surface temperature is below 200°C, the HPC™-HT resin will not dry and will remain soft.

HPC®-HT is the recommended for high-temp insulation applications when the surfaces temperature is greater than 482°F (250°C). HPC®-HT is ideal to insulate and to prevent Corrosion Under Insulation  (CUI) when used on  all hot surface and processes such as hot pipes, tanks, valves boilers and more. HPC®-HT is designed to hold the heat on the surface of the pipe, tank, valve, boilers , etc..

HPC-HT is top coated with one of our approved top coats that do not breathe and prevents moisture infiltration (SP Seal Coat HT or Super Therm is recommended). This creates an air and moisture tight installation system with no air gaps or seams. The top-coats, SUPER THERM®, RUST GRIP®, ENAMO GRIP or Sp Seal Coat can be used in accordance to what is needed.

HPC®-HT  Coating  is  a  two-component  product that is applied using a Graco texture sprayer GTX 2000 EX. For specific instructions on surface preparation, mixing and application, please refer to the HPC®-HT Coating Application Instruction Sheet.
