Tributyltin acrylate is primarily used as a biocide in antifouling paints applied to ship hulls, underwater structures, and fishing nets to prevent the growth of marine organisms like algae, barnacles, and mollusks. Its effectiveness in inhibiting biofouling helps maintain vessel efficiency and reduces fuel consumption. Additionally, it finds application in industrial coatings and polymers, where it acts as a stabilizer and antimicrobial agent, enhancing the durability and lifespan of materials. However, its use is increasingly restricted due to environmental concerns and toxicity to non-target marine life.
