Extended Operational and Trade Vocabulary
Marine Coatings, Antifouling, and Hull Husbandry glossary (page 2)
Vocabulary of marine coatings and hull maintenance: ablative and self-polishing copolymer antifoulings, anti-corrosive primers and airless spray application, the AFS Convention controlling harmful anti-fouling systems and its MEPC.334(76) cybutryne ban, and the biocide-release, surface-preparation and hull-husbandry terminology of protective marine paint systems.
