HERESITE COATING

At Rahn Industries, we have been a Heresite™ certified licensee since 2015, providing immersion/dip & bake coatings in addition to spray-on options for our customers. We also perform disassembly and reassembly of HVAC units & parts to apply coating inside and out.

P-413 Baked Phenolic Epoxy Heresite Coating

Heresite P-413 is a thin high performance protective coating used mainly for ac coils radiator heat exchangers. The corrosion resistance of this coating significantly extends the life of HVAC units. Heresite P-413 withstands marine and salt air environments, exposure to an extensive variety of high and low pH corrosive and chemical fumes and condensate, while performing as a thermal conductor.

Heresite is recommended for use in light gage metal, especially products made of aluminum, stainless, copper, and carbon steel.

Heresite coating is applied by an immersion process (dip & bake) where the coil/equipment is immersed in the protective coating, and then after being removed from the solution it is baked in an oven to cure. This process produces a very durable coating that thoroughly protects inside and outside protection for your coil/equipment.

ES-606 Epoxy-Silane Heresite Coating

The ES-606 is a high-performance, robust spray-applied coating used to protect heat transfer equipment and components like coils and cabinets. It is an excellent choice when a full-immersion product like the P-413 cannot be used.

This product is applied directly to the metal and has excellent corrosion, humidity, and UV resistance, along with good adhesion to ferrous and non-ferrous metals. It can be used in internal and external surfaces of HVAC coils and equipment.
