Antifouling
SigmaEcofleet
The based around technologies to give products with better control over biocide
release. Sigma EcoFleet antifouling coatings also have extra co-biocides to improve
fouling resistance, particularly against algae. Sigma EcoFleet film properties are
good and 2-3 coats can be specified at dry film thicknesses up to 150 μm. The leached
layer is more controlled, and typical projected service lifetimes are up to 36 months
for deep-sea vessels, with up to 60 months possible for certain situations/operating
conditions.

cause the fouling to detach.
