FAQ

What coating thickness is required for corrosion activity category C3?

To answer this question, it is necessary to clarify the intended service life. There are three categories: low up to 7 years, medium from 7 to 15, high from 15 to 25 and very high over 25 years. For example, taking a medium service life, in this case when using epoxy primer (zinc‑free) and polyurethane enamel, the total coating thickness will be 180 µm.
