Hot Surface Coating (HSC™)

Get heat protection/insulation that surpasses conventional insulation with HSC™ Coating, a ceramic based, water-borne insulating coating designed to insulate in medium temperature situations. Use HSC™ Coating as a base coat/primer or build layers for additional protection.

HSC™ is used to coat over pipes or surfaces that load up to 175°C. The coating is not a reflective coating, but works to block the loading of heat into itself and resist the transfer of this heat through the coating to the cooler side. Single component water based.

Hot Surface Coating (HSC) is a design of several specially formulated resins and additives created to provide a base that is flexible enough to withstand severe climate changes, as well as severe heat peaks without loss of adhesion. A select group of ceramic materials are used in the formula to achieve a stoppage of heat, fire, smoke, and gases from passing through the coating during a fire.

This coating is designed to stay intact with constant adhesion above 1090°C. This is not an intumiscent coating, but instead, a pliable film that reacts to flame. The face of the coating will glaze during a fire to form a complete protection shield against flame, smoke, gases and heat.

This insulation method is much different than the traditional “wrap” insulation materials that only slow down the loss of heat (known as an R-rating or “heat transfer”). The seven ceramic compounds create a barrier to catch and hold heat on the surface of the unit, e.g. pipe, furnace surface, boiler, etc. Unlike wraps that use air as the insulation component, the ceramic compounds in the HSC™ Coating resist absorbing heat trying to come off the surface to escape. This traps and holds the heat onto the surface for more effective insulation performance.

Instead of just measuring the heat on the surface, the question should be: What is the heat inside the unit? The answer: After coating, the surface will equal the temperature inside.

Additional benefits of HSC™ Coating include:

Easy to Apply: Apply directly to hot pipes up to 325°F (162°C) while operating with brush, roller or airless sprayer.

Increased Insulation: Additional coats immediately reduce surface temperature and loss of heat.

Long Lasting: Does not absorb moisture or lose insulation value.

Safe: Non-flammable and non-toxic.

Coverage: Can be brushed or sprayed to fit over any configuration or shape.
