Overview

Troysan® 866 is a powerful, broad-spectrum in-can preservative designed to protect water-based products from microbial contamination during storage and usage. Developed by Arxada (formerly Troy Corporation), Troysan® 866 combines multiple active isothiazolinones to offer strong antibacterial and antifungal protection against spoilage organisms. It is especially effective in high-risk formulations such as paints, coatings, adhesives, emulsions, and latex-based products. With excellent compatibility and performance at low use levels, Troysan® 866 enhances product shelf life while maintaining compliance with regulatory standards for industrial and consumer applications.
