HERESITE COATING
SUPPORT AND DOCUMENTS REQUEST A CUSTOM QUOTE
Since 1954, Heresite™ has produced corrosion coating products that deliver high performance protection with maximum efficiency. Heresite products obtain superior chemical resistance properties and are the top choice for harsh environments.
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.
