What you need to know about ISO Corrosivity Categories

Corrosion testing on HVAC coatings can be conducted according to a number of standards, including ASTM-B117, ISO 9227, ISO 12944-6, and ISO 20340. Of these tests, the one we believe represents actual service environments most closely is ISO 12944-9 (formerly ISO 20340) vs. the more common ASTM B-117. ISO classifies

What is salt spray testing and how does the process work?

Salt spray testing is a laboratory simulation of a corrosive saline environment. It is used as an accelerated means of testing the ability of surface coatings to withstand atmospheric corrosion. Also known as salt fog testing, it is one of the oldest testing methods used in the HVAC-R coatings industry,

Heat transfer test results for Heresite’s P-413

Heat transfer is an important consideration when selecting a protective coating for HVAC-R condensers or evaporators. A protective coating, when applied properly, can extend the life of HVAC-R coils by preventing corrosion with negligible impact on heat transfer. In 2017, we participated in a wind tunnel test for our P-413
