HPC™ Coating: Specs and Uses

Uses:

Reduction of external temperature of hot surfaces as an aid to worker safety
Reduction of heat loss for energy savings
Stops condensation
Stops CUI (corrosion under insulation)

Application

Although HPC™ Coating can be applied by non-professionals, SPI recommends using a SPI certified applicator.

Preparation:

Surface must be clean and completely dry, with no loose debris or particles, rust, dirt, oil, films or residues of any kind. HPC™ Coating will cover previous coatings, provided they are fully adhered to the surface and no gloss surface
Mechanically stir, as formula will tighten and give the appearance of cake or putty. Stirring loosens and relaxes the consistency.

Application methods:

Graco Texspray RTX 1500 using 2mm nozzle
Over hot surfaces apply a 50 wet mil (1.25 mm) primer coat to allow a steaming-off and cooling of surface to avoid bubbles, and then increase thickness with additional coats as needed

Applied rate:

80 sq. ft./gal. (7.4 sq.m./gal.) as primer
2.4 - 9.6 sq. ft./gal. (0.22 – 0.9 sq.m./gal.) with build coats (125 mils - 500 mils dry per coat)

Film thickness:

50 mil wet (1.25 mm) as primer
125 - 800 mils dry (3 – 20 mm) with build coats depending on need to control different ranges of heat
Fire Control System 800 mils - 1600 mils (20 mm - 40 mm) as the primer before Omega Fire™ top coat.

Dry times:

10 minutes as primer over hot surface, then increase thickness as needed.
24 hours to set

Precautions:

Do not use for exterior applications unless top coated with Super Therm® for long term durabilit

Limitations:

Do not use for underwater applications.
HPC™ Coating is light yellow in color and rough in texture
Not recommended as the only fire protection material to be used in residential or industrial construction
Do not use as floor coating
Not UV protected. For external use overcoat with Super Therm®
