HPC® Coating

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 an insulation to block heat loss or for employee protection.

HPC® Coating – single component water-based coating designed to insulate hot pipes or surfaces that load up to 260°C (500°F). The coating is not a reflective coating, but works to block the loading of higher heats and to resist the transfer of heat through the coating to the cooler side.

Holds heat on the surface in which it covers. Always ask what the temperature inside the unit is and not the heat on the surface. Once coated, the surface will be equal to the interior temperature which could be 93-148°C (200-300°F) higher than what is registering on the exterior. Learn More SPI >

Video above shows HPC® Coating being applied in 2011 at Gazprom (Russia’s largest LPG Energy supplier to Europe) and shows a 550°C hot pipe insulated down to less than 40°C in just minutes…all without a shutdown or hot permit. Manufactured by Superior Products International (SPI), Hot Pipe Coating (HPC) is available from NEOtech Coatings Australia.

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 HPC® Coating 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.

HPC® 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. 25mm (1 inch) over a 232°C (450°F) pipe allowed someone to touch the surface safely 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.

HPC for Cool Room Condensation – 30°C variation

The Challenge: A client was looking to stop condensation on a wall that was an office and the room was 22°C. The other side of the wall was a cool room at -15°C with panelling. Both walls are interior to the building however for this conversation the office wall is the exterior wall.

HPC Solution from SPI Coatings

When you get over a 30 degree difference between the interior and exterior of a wall, you need some thickness, so you are only interested in the exterior side of the wall.

Why, because the hot moisture air is only on the exterior wall.

When the warm air hits the wall and sets, it cools and when it cools, it cannot hold the moisture and it shows as condensation on the side of the warm air. As warm air cools, it drops out it’s moisture.

The interior is cold and no moisture as the air conditioning unit pulled all the excess moisture out of the air and cool air does not hold moisture. You must prevent the warm moist air from setting on the cold common wall between interior and exterior.

To do this, you must apply HPC for thickness to 13mm dry thickness and over coat with Super Therm®.

This blocks the warm air from setting on the surface of anything cool, the Super Therm® helps to throw off the radiation by using emissivity to release the warmth off the surface.

You must have the thickness of the HPC to prevent the wall surface with Super Therm® on it to ever being cool that would cause the warm air still covering the exterior wall during the warm air laying on the wall and then being thrown off by Super Therm®.  You would still have some condensation without HPC.
