Few environments are tougher on metal than the Hawaiʻian coast. Salt water, persistent humidity, strong UV, and constant moisture exposure attack uncoated steel within months. Add the regulatory shift away from copper-based antifouling, and marine operators need a coating system that handles all of it — without dumping toxic chemicals into the water.
SPI’s marine line carries approvals from DNV, ABS, the AWWA (American Water Works Association), and the IMO. Different products handle different parts of a vessel:
| Application | Product |
|---|---|
| Submerged hull (below waterline) | Moist Metal Grip |
| Whole-hull primer (above and below waterline) | Rust Grip® (DNV approved) |
| Above-waterline topcoat (color) | Enamo Grip® |
| Wheelhouses, top decks, electronics | Super Therm® (DNV approved) — heat + sound |
| Engine rooms, fire spread prevention | Omega Fire (DNV approval pending) |
| Hot pipes and boilers (live operation) | HPC® |
| Interior of acid or caustic tanks | Lining Kote UHS |
| Indoor potable-water tanks | Moist Metal Grip (AWWA approved) |
A Moist Metal Grip + Enamo Grip® system delivers permanent non-stick antifouling protection:
The largest U.S. Coast Guard approved casino vessel ($163M build) used five SPI coatings:
Super Therm® cuts sound by 50–68% through hulls and interior walls — useful on wheelhouses, sleeping quarters, and engine compartments where noise is a fatigue issue on long passages.
