Why use a hydrophilic HVAC topcoat?

in Coatings

Management of condensation and moisture is critical to ensuring the efficient function of HVAC equipment. Equipment operating in high temperature, submerged, or salty environments can suffer from condensation issues, which exacerbate the corrosion process, or lead to the creation of large waer droplets, which force the fan to work harder. Hydrophilic (or water-loving) coatings or […]
