HPC
HPC® Coating is designed to control heat transfer on surface temperatures up to 482°F (250°C). It is water-borne and extremely lightweight in appearance. HPC® Coating uses a special acrylic resin blend with specific ceramic compounds added to provide a non-conductive block against heat transfer. HPC® Coating offers a “Green”, non-flammable, non-toxic formula for high heat surface applications over standard steam pipe or oven wall construction. HPC® Coating is easily applied using a texture sprayer, and can be applied over metal, concrete, wood, and other substrates.
If HPC® Coating is to be applied over flat steel surfaces, see manufacturer for instructions.

Application Methods
HPC® Coating can be used for applications ‘up to’ 482°F (250°C). It must be applied according to Manufacturer’s Application Instructions.
The application is applied using a texture sprayer. For specific instructions on surface preparation, mixing and application, please refer to the SPI Application Instruction sheet for HPC® Coating. If HPC® Coating is applied on surfaces outdoors, you must overcoat the HPC with Super Therm®, Rust Grip®, SP Liquid Membrane or Enamo Grip according to what is needed. It cannot be left uncoated and left exposed to weather conditions. It is light-weight to insulate, which leaves it vulnerable to weather conditions. HPC® Coating must be completely dry before applying top coat.
HPC® Multi-Mesh Membrane System is used on hot pipes when continuous cycles cause movement, and where continuous impact caused by workers handling the hot pipe is unavoidable. Apply Multi-Mesh Membrane between layers of Rust Grip, Enamo Grip or Moist Metal Grip for exterior toughness. Multi-Mesh Membrane combined with Rust Grip or Moist Metal Grip forms a hard cast for exterior strength and moisture barrier to protect the HPC system. A final top-coat of SP Liquid Membrane should be added for impact resistance and movement from elongation during heat cycles to avoid stress cracks.
