Get heat protection that surpasses conventional insulation with HSC™ Coating.  HSC™ Coating is a ceramic based, water-borne insulation coating designed to insulate and control conductive heat transfer on surface temperatures up to 350°F.

HSC™ offers a “green”, non-flammable, non-toxic formula that can be used for applications requiring smooth surfaces over small diameters.  It can be applied over metal, concrete, masonry, wood, and other substrates.  HSC™ is an ideal thermal coating for hot surfaces with irregular shapes such as elbows, joints, valves, tanks, or in tight spaces that are difficult to reach.

HOT SURFACE COATING is a ceramic based, water-borne insulator designed to insulate in medium temperature situations. HOT SURFACE COATING can be used as a base coat/primer or it can be built up layers for additional protection. HOT SURFACE COATING is specifically engineered to control hot surface temperatures up to 350°F .

  • Easy Application – airless spray, brush, roll
  • Weatherability – no topcoat required
  • Longevity – does not absorb moisture
  • Esthetics – Lightweight and smooth in appearance
  • Superior Insulation – 0.07 W/mK
  • Cold Insulation – Condensation Control
  • Corrosion Protection – Helps control CUI (Corrosion Under Insulation)
  • Safe – Water based and USDA approved for food contact

HOT SURFACE COATING (HSC) insulation method is much different than the traditional “wrap” insulation materials which merely slow down the loss of heat (known as an R rating or “heat transfer”).  The seven ceramic compounds in HSC™ create a barrier to catch and hold heat on the surface of the unit; whether a pipe, furnace surface, boiler, etc.  While HPC is designed for high heat, HSC is designed for medium heat up to 350°F .  

Unlike conventional wraps that use air as the insulation component, the ceramic compounds in HSC™ Coating resist absorbing heat radiating from the surface.  This traps and holds the heat onto the surface for more effective insulation performance.

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.
