Are you getting the HVAC-R coating you expect?

For over 80 years, Heresite coatings have been used to protect HVAC-R equipment in the harshest environments. We’re proud of our history, and we’re proud to continue to offer products like P-413, which recently met the demanding offshore marine requirements of ISO 20340.  These are tested, proven, real-world results.

Unfortunately, being an early innovator and a market leader means that sometimes our company’s name or products are used generically across the entire coatings industry. Much like facial tissue or fruit-flavored gelatin, the words “Heresite” or “phenolic” are often used to describe Heresite coatings such as our P-413 or VR-514. You may have also heard the word “phenolic” used to describe a combination of our air-dry phenolic coating (VR-514) applied over an e-coat base.

It’s important to know that use of a Heresite air-dry phenolic coating over an e-coat base is not a true phenolic coating.

Both P-413 and VR-514 are phenolic coatings. They have different performance specifications due to their cure mechanism. The P-413 is a baked, fully cross-linked phenolic, while VR-514 is an air-dry phenolic.

The application of Heresite VR-514 air-dry over an e-coat base is not a baked phenolic coating. Although VR-514 is a well-tested phenolic coating that is effective in marine and salt air environments, it does not offer the superior level of marine/salt air, chemical or temperature resistance as P-413. Both coatings have been extensively tested using prescribed application methods. We have not tested the performance of VR-514 over an e-coat base.

To achieve the best possible coating performance in the field, your HVAC-R coatings should be applied using proven combinations of base and top coats. We know performance and tested, proven results matter. We’re always happy to help you select the right coating for your particular situation. Give us a call anytime. We’re here to help.
