• Antifouling agent preventing biological colonization on submerged and exposed surfaces
• Marine and industrial antifouling paints: co-biocide
• With copper compounds to broaden protection against algae and slime-forming organisms
• Hull paints, dock coatings and offshore structure treatments
• Architectural and industrial coatings: protects exterior surfaces from algal discoloration and extends service life
• Sealants and elastomers for outdoor construction incorporate it to prevent surface biofilm development
• It is effective in high-humidity environments.
