Two‑component epoxy primer‑finish coating with a non‑volatile solids content of 76 % and zinc phosphate, providing excellent anticorrosion protection. Fast curing, ideal for high‑productivity application in shop environments at temperatures down to −10 °C.
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.
Part 2 (ISO 12944-2).
ISO 12944 standard describes condition C3 as moderate in environmental aggressiveness. Typically it refers to urban and industrial atmospheres, moderate sulfur dioxide pollution. Coastal areas with limited salt exposure.
