Beyond the Hype – The Reality of E-Coatings

A lot is riding on the protective coating you select for your HVAC-R equipment. It needs to provide a shield against corrosion, guard units from environmental pollutants, and even make them pleasant to look at.

The Heresite P-413 high performance coating is the industry standard in the HVAC-R world. It’s a thin film that protects the coil, radiator, heat exchangers, and other air and fume-handling equipment made of light-gauge metals. While Heresite P-413 has no direct competitors, e-coating is often considered a suitable alternative for high-performance coating needs. But is e-coating in the same ballpark with Heresite?

E-coating, short for electrodeposition coating, is a process of applying a protective layer to a metal object using an electrical current. It’s used for providing a uniform and corrosion-resistant finish on metal surfaces. It is known for its even coverage and ability to protect complex-shaped objects from corrosion.

So which one should you choose?  Let’s take a look. 

Both products do well with chemical, pH, and corrosion resistance, but Heresite clearly outperforms e-coating in three very significant areas:

When choosing protective coatings for your HVAC-R systems, why not select the one that performs the best in the industry! Heresite’s P-413 has been proven to significantly extend the service life of the components it coats, especially in severe offshore marine environments. It also withstands exposure to a wide variety of high and low-pH corrosive and chemical fumes and moisture.
