Hot Surface Coating

HSC (Hot Surface Coating) is the cost efficient, lower temperature control product to HPC (listed above). Designed for operating temperatures from 150F to 300F both HPC and HSC are ceramic non-conductive coatings built for specific thermal control. HSC is designed and engineered for thermal needs below 300F where HPC was developed for thermal applications exceeding 300F to 1500F. (A new Hi Temp version of HPC is being developed that will control thermal temps up to 3000F.)

HSC (due to its thermal range) is less expensive than HPC, however both coatings are far more cost effective, longer lasting and offer better thermal/energy control than using traditional insulation/cladding methods.

HOT SURFACE COATING is a water-borne system using a special acrylic blend with specific ceramic compounds to provide the non-conductive block against heat transfer without depending upon reflectivity. The coating will dry down on a cold surface by evaporation and can be aided in the dry down by adding heat to the environment. If the surface is already heated, the dry-down process will take care of itself without additional steps required.


The HOT SURFACE COATING insulation method is very different to the traditional “wrap” insulation materials that only slow down the loss of heat (known as an R-rating or “heat transfer”). The seven ceramic compounds in the HOT SURFACE COATING 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 the HOT SURFACE 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.


HOT SURFACE COATING was designed for applications whose temperature exposures falls below 177°C and can be applied to metal, concrete, masonry and wood. HOT SURFACE COATING is safe, non-flammable and non-toxic.

HOT SURFACE COATING has been successfully tried and tested throughout the world and has received numerous certificates to substantiate its effectiveness and reliability. For updated SDS and/or further information regarding these different test results please contact us.

HOT SURFACE COATING’s compound structure has proven in the field to offer superior results when compared to traditional “wrap” insulators.
