Reviewing Requirements for Powder Coatings Rated for Food-Grade Applications

摘要

Q: We powder coat formed wire products, 1008/1010 material. The powders are epoxy and polyester hybrid/TGIC/types. How long must we wait, after cure, to (a) test for Crosshatch adhesion and (b) before we do the MEK rub tests? If we recoat over a thin coat, will that affect the cure time, affecting the same tests?
