AkzoNobel’s protective coatings brand, International, has released a study revealing that protective coatings with a higher lamellar glass flake content are the most effective for the long-term protection of offshore structures.
Performance against corrosion offshore is dependent on minimizing the propensity for damage during construction and in operation.

“There is a growing need and demand for extending the lifetime of offshore assets as the sector experiences increased investment. Today’s research is proof that there is a clear correlation between lamellar glass flake content and the durability of a coating,” said Willem Horn, O&G upstream and wind energy sub-segment manager. “With a 40-year track record and proven real-life performance, Interzone 1000 shows how epoxy solutions from International remain the trusted and go-to technology for protecting offshore assets worldwide. Its optimized formulation has been proven to deliver unmatched durability, extending asset life and reinforcing confidence in sustainable energy transition, protecting more than 4,000 offshore assets globally.”
Glass flake is typically added to coating formulations to provide more robust films in protecting against impact and abrasion. The study examined the impact of varying concentrations of lamellar glass flake on the durability of its epoxy-based coating, Interzone 1000. Epoxy is the most widely used technology for protecting assets in the offshore sector and alongside its proven longevity of track record, minimizes HSE risks of using polyester in initial fabrication.
In addition to this lnternational study, the long-term impact of the coating has been monitored on the Hutton Tension Leg Platform (TLP) in the North Sea off the east coast of Scotland for the past 40 years.
Interzone 1000 was applied to the Hutton TLP in 1982. Inspections at its 30- and 40-year mark have confirmed the coating’s integrity, showcasing its exceptional resistance to corrosion and wear in extreme offshore conditions.
