Heavy-Duty Anti-Corrosion Coating for Industrial Steel: What C5 Actually Requires
‘Heavy duty’ is one of those terms that appears on a lot of coating product labels and specifications without a precise meaning. Every manufacturer seems to have a ‘heavy duty’ epoxy. Not all of them perform the same way in genuinely aggressive industrial environments. In the ISO 12944 framework, the term maps reasonably well to category C5 […]
Organic vs Inorganic Zinc-Rich Primer for Structural Steel: Which One Should You Specify?
Both organic zinc-rich primers (zinc-rich epoxy) and inorganic zinc silicate primers provide galvanic corrosion protection to structural steel. Both contain high levels of metallic zinc dust. And yet they’re meaningfully different products with different performance profiles, different application requirements, and different appropriate uses. In practice, organic zinc-rich epoxy is specified for the vast majority of […]
Anti-Corrosion Coating for Steel in Coastal and Marine Environments: How to Specify for the Conditions
Coastal and marine environments are where anti-corrosion coatings are most challenged — and most frequently underspecified. The combination of salt-laden air, humidity, UV exposure, and in some locations direct wave splash creates corrosion rates many times higher than inland industrial environments. A C4 coating system that would last 20 years in an urban industrial setting […]
