Description

Tralopyril CAS NO 122454-29-9 is a highly effective organic biocide belonging to the pyrrole class of compounds. It matters as a key active ingredient in marine antifouling paints, where it prevents the growth of algae, barnacles, and other organisms on ship hulls, improving fuel efficiency and reducing maintenance costs. This product is essential for manufacturers of marine coatings, aquaculture equipment, and industrial water treatment systems seeking a potent and environmentally considered alternative to traditional copper-based antifoulants.

Application

• Marine Antifouling Paints: Primary active agent in self-polishing copolymer (SPC) and free association antifouling coatings for commercial shipping, naval vessels, and recreational boats.
• Aquaculture Netting & Equipment: Incorporated into polymer matrices for nets and cages to inhibit biofouling, ensuring optimal water flow and animal health.
• Industrial Cooling Water Systems: Used as a biocide to control algal and bacterial growth in cooling towers and heat exchangers.
• Wood Preservation: Acts as a fungicide and insecticide in preservative formulations for outdoor and marine timber structures.
• Antifouling Gel Coats & Films: Formulated into coatings for sensors, underwater instruments, and offshore infrastructure.
• Research & Development: Serves as a reference standard and active material in the development of new biocidal products and environmental fate studies.
