HSC™ 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
  • Helps to stop CUI (corrosion under insulation) by blocking heat loss

Application

Although HSC™ 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. HSC™ Coating will cover previous coatings, provided they are fully adhered to the surface and no gloss surface
  • Mechanically stir, as formula will tighten. Stirring loosens and relaxes the consistency.

Application methods:

  • Graco Texspray RTX 1500 or airless sprayer (2,800 psi minimum with .035 tip)
  • 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
  • 4.8 - 9.6 sq. ft./gal. (0.44 – 0.9 sq.m./gal.) with build coats

Film thickness:

  • 50 mil wet (1.25 mm) as primer
  • 125 - 250 mils dry (3 – 6 mm) with build coats depending on need to control different ranges of heat. Build up to meet need.

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 Rust Grip® or Enamo Grip for long term durability

Limitations:

  • Do not use for underwater applications.
  • HSC™
    • Coating is white 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®
