Industrial coatings for steel
Zinc-rich primers, epoxy build coats, polyurethane topcoats and tank linings for steel structures, tanks and pipelines.
Pick the system by ISO 12944 corrosivity category, C2 to CX.
Which corrosivity category
ISO 12944-2 categories, with the environments the standard names for each.
Category C2: Low
Unheated buildings where condensation can occur; rural atmospheres
Category C3: Medium
Urban and industrial atmospheres with moderate sulphur dioxide; coastal areas with low salinity
Category C4: High
Industrial areas and coastal areas with moderate salinity; chemical plants
Category C5: Very high
Industrial areas with high humidity and an aggressive atmosphere; coastal and offshore areas with high salinity
Category CX: Extreme
Offshore areas with very high salinity; industrial areas with extreme humidity and an aggressive atmosphere
