Sigma EcoFleet 290
Sigma EcoFleet 290 by PPG Sigma is a marine underwater-hull self-polishing antifouling coating. It forms part of a complete coating scheme over prepared and compatible anticorrosive layers rather than functioning as a stand-alone paint. The supplied record lists Coverage 6-8 m2/L; actual application requirements must still follow the current product data sheet and approved specification. Performance depends strongly on surface preparation, dry-film build, overcoating compatibility, curing conditions and the vessel's operating profile. Damage from blocks, fenders, grounding or underwater cleaning can locally interrupt the designed surface behavior. Neighboring products in the same coating family may target different service speeds, fouling risk or maintenance strategies, so substitutions require system-level confirmation from the manufacturer.

Common failures & inspection points
Service & Maintenance
Inspect the underwater hull during dry-docking and available underwater surveys, mapping mechanical damage, fouling and coating breakdown. Repairs should follow the complete manufacturer system, including cleaning, preparation, primers/tie coats and finishing coats as applicable. Control environmental and application conditions from the current product data sheet rather than using generic values. Record batch numbers, areas repaired and coating-system details in docking documentation. Class normally focuses on hull condition rather than coating performance alone, but coating breakdown may expose corrosion or structural defects that require survey attention.
