Although many tests exist to help measure the potential performance of HVAC-R coatings, at Heresite we believe in cyclic testing to estimate a product’s performance in real-world conditions. We are proud to say that P-413, our thin film corrosion resistant coating, was the first HVAC-R coating to successfully meet the demanding requirements of the ISO 12944-9 cyclic test. Heresite’s ES-600 high-performace epoxy-silane has also been tested using ISO 12944-9 and has demonstrated superior performance in demanding CX environments. ISO 12944-9 (formerly ISO 20340) tests the coating by cycling between salt spray, UV radiation and freezing temperatures for 25 weeks.
Unlike other tests, the ISO 12944-9 is a cyclic test, which mimics real world environments much more realistically. While lab conditions can only approximate real-world corrosivity, we feel that ISO 12944-9 provides a more accurate result than B 117, which is a static test. Marine environmental conditions change constantly. For this reason, we have tested P-413 and ES-600 against both B 177 and ISO 12944-9 to help our customers predict coating effectiveness in their particular environments.
In addition to ISO 12944-9 (formerly ISO 20340), Heresite coatings have been tested using the following testing methods:
