Used primarily as a crosslinking agent in the production of high-performance polymers, particularly in the synthesis of polyurethane and epoxy resins. It enhances the thermal stability and mechanical strength of these materials, making them suitable for demanding applications such as coatings, adhesives, and composite materials. Additionally, it serves as an intermediate in the manufacture of organic sulfur compounds, which are utilized in various industrial processes, including vulcanization of rubber and as antioxidants in lubricants. Its role in improving the durability and performance of materials makes it valuable in industries requiring robust and long-lasting products.
