Heresite P-413 is a thin film, high performance coating used principally for coil and radiator heat exchangers as well as other air and fume handling equipment fabricated of light gauge metals. It is the first HVAC-R coil and radiator coating to meet the ISO 12944-9 (formerly ISO 20340) Standard for severe offshore marine environments. The corrosion resistance of Heresite P-413 coatings significantly extends the service life of HVAC-R (heating, ventilation, air conditioning, and refrigeration), and other heat transfer equipment.
In addition to marine and salt air environments, the P-413 family of coatings will withstand exposure to an extensive variety of high and low pH corrosive and chemical fumes and condensate. Because these products are efficient thermal conductors, applied at very thin films, HVAC-R and process equipment coil OEMs have indicated that thermal loss due to the presence of P-413 baked phenolic epoxy coating is <1%.
