Antifouling Coating · Paint & Coating Systems
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. 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.
