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 […]
