HOT SURFACE COATINGTM TECHNICAL SHEET
DESCRIPTION
HOT SURFACE COATING is designed to control heat transfer on surface temperatures up to 350 F degrees (176oC). It is water-borne, and extremely lightweight and smooth in appearance. HOT SURFACE COATING uses a special acrylic resin blend with specific ceramic compounds added to provide a non-conductive block against heat transfer. HOT SURFACE COATING offers a Green , non-flammable, nontoxic formula for medium heat surface applications over standard steam pipe or oven wall construction. The coating was originally designed for hot applications where temperature exposures fall below those that would require the use of HOT PIPE COATING. HOT SURFACE COATING is more easily applied for a smooth finish. It can be applied over metal, concrete, wood, and other substrates. TYPICAL USES
As an insulation system over hot pipes, tanks, and valves
To block heat migration into cold tanks, lines, and valves
Easily applied when a hot system cannot be shut down
APPLICATION METHOD
HOT SURFACE COATING should be used for applications 350 F degrees (176oC) or lower. Apply HOT PIPE COATING for applications between 350 F degrees (176oC) and 700 F degrees (371oC). HOT SURFACE COATING can be applied to metal, concrete, masonry and wood. The application can be by spray, brush or roller. For specific instructions on surface preparation, mixing and application, please refer to the SPE Application Instruction sheet for HOT SURFACE COATING. If HOT SURFACE COATING is applied on surfaces outdoors, you must overcoat the HOT SURFACE COATING with SUPER THERM, RUST GRIP, ENDUROOF or ENAMO GRIP according to what is needed (please contact SPE for further instructions). It cannot be left uncoated and left exposed to weather conditions. It is light-weight to insulate, which leaves it vulnerable to weather conditions.
NOTE: In situations where there is continuous cycles causing movement, and/or risk of contraction and/or expansion, or regular handling of the pipe is unavoidable, please contact SPE for further instructions to support the application of HOT SURFACE COATING. TESTS AND CERTIFICATIONS

before charring and blocking the flame.
SAFETY PRECAUTIONS
Do not take internally. Avoid contact with eyes. If solution does come in contact with eyes, flush
immediately with water and contact a physician for medical advice. Avoid prolonged contact with
skin or breathing of spray mist.
KEEP OUT OF REACH OF CHILDREN.
