Coreline bought a set of new expoy power paint equipment at the beginning of 2015. After months of tests, the new painting system has proven superior quality on our valves.

Coreline Epoxy 521H is hard, impact resistant and solvent resistant. This coating provide long-term protection to products designed for interior service environments. When the thermoset epoxy  powder is exposed to elevated temperature, it begins to melt and flow out, then chemically reacts to form a higher molecular weight epoxy in a network-like structure. This cure process, called crosslinking, requires a certain degree of temperature for a certain length of time in order to reach full cure and establish the full film properties.
