In this way, what is the purpose of epoxy primer?
Epoxy primer is a sealer that produces a good surface finish on applied top coats. A two-part epoxy primer contains zinc phosphate, which acts as corrosion-inhibiting pigment. Epoxy primers can be used to waterproof materials that consequently protect the bare metal from oxidation.
How do you apply epoxy primer?
The epoxy primer should be applied in medium wet coats, allowing a half an hour between each coat at around 70 degrees. One to two coats will render a one millimeter dry film thickness, which is typically enough to be completely effective. Make sure to evenly spray each coat completely across the bare metal surface.
