HPC®-HT can be applied to high-temperature surfaces up to 600°C. HPC®-HT is a two-part hybrid silicone/solvent resin (Part B is flammable) and (Part A is water-based resins) using specific ceramic compound loads for application directly over surface 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. HT Primer is applied first for best adhesion.
- 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 Is designed to block and hold the interior temperature on the surface and reduce heat transfer loss to ambient.
|Product Chemistry||Silicon Based|
|VOC Level||200 g/L, 1.67 lbs./gal.|
|Dry Time (at 400-650˚F)||20 minutes per coat|
|Cures By||Evaporation on hot surfaces|
- As the high-temp insulation coat for surfaces greater than 250°C, over hot pipes, tanks, and valves
- To hold heat on the surface of the pipe, valve, etc.
- As a system to block conductive and convective heat transfer
- Applied when a hot system cannot be shut down
CAUTION: Do not expose Part B to open flame as solvent used to allow silicones to blend faster. After Parts A and B are blended, product is non-flammable for use in spraying direct to hot surfaces reaching 650°C
For specific instructions on surface preparation, mixing and application, please refer to the HPC®-HT Coating Application Instruction Sheet available upon request. If HPC®-HT is applied over hot exterior surfaces, and can be over-coated, Super Therm®, Rust Grip®, Enamo Grip or HPC system topcoat can be used according to what is needed.
HPC®-HT must be completely dry before applying topcoat. HPC® Multi-Mesh Membrane System or high-temp mesh can be used on hot pipes when continuous cycles cause movement, and where continuous impact caused by workers handling the hot pipe is unavoidable. PRIME FIRST: Use HT Primer over the hot surface after cleaning off hot pipe surface from debris. Spray on a thin coat (3mm/120mils) to seal the surface and give an adhesive layer for the insulation coating (HPC-HT). See HT Primer tech sheet.
