Hot Pipe Coating (HPC™)

HPC™ is used to coat over pipes or surfaces that load up to 425°C. The coating is not a reflective coating, but works to block the loading of higher heats into itself and resist the transfer of this heat through the coating to the cooler side. Single component water based.

Get "high" heat protection that surpasses conventional insulation with HPC™ Coating. HPC™ Coating is a ceramic based, water-borne insulating coating designed to insulate in high temperature situations. Use HPC™ Coating as a base coat/primer or build layers for additional protection.

This insulation method is much different than the traditional “wrap” insulation materials that only slow down the loss of heat (known as an R-rating or “heat transfer”). The eight ceramic compounds create a barrier to catch and hold heat on the surface of the unit, e.g. pipe, furnace surface, boiler, etc.

Unlike wraps that use air as the insulation component, the ceramic compounds in HPCCoating resist absorbing heat trying to come off the surface to escape. This traps and holds the heat onto the surface for more effective insulation performance.


Hot Pipe Coating test

A test on a heating pipe showing the powerful properties of ceramic insulation technology. Part of the pipe is painted with our Superior Products ceramic coating to show the comparison of the thin insulative film. Footage shows pipe reducing from 232°C (450°F) to 35°C (95°F) during application.

Additional benefits of HPC™ Coating include:

Easy to Apply: Apply directly to hot pipes while operating. Spray with hopper guy or Graco 1500 TexSpray. Apply thin coats first, and after surface reduces heat level, thicker coats can be applied.

Increased Insulation: Additional coats immediately reduce surface temperature and loss of heat. One inch over a 900°F (478°C) pipe allowed someone to touch the surface at 60°C.*

Long Lasting: Does not absorb humidity or lose insulation value with overcoat of Super Therm®.

Safe: Non-flammable and non-toxic.

Coverage: Can be sprayed to fit over any configuration or shape.


* This was in Siberia in the winter with the ambient temperature at -30°C. In normal circumstances, we have to apply a minimum of 50mm (2”) of HPC™ to contain the heat and prevent the char of the resins from reaching the exterior side of the coating. All hot pipes are analyzed using engineering formulas to determine the thickness of coating to use for the ambient temperatures and size of the pipes or vessel.
