Bis(2-mercaptoethyl) ether is primarily used as a crosslinking agent in the production of polymers and resins. It is particularly valuable in the synthesis of polythioethers, which are known for their excellent chemical resistance and mechanical properties. This compound is also employed in the formulation of adhesives and sealants, where it enhances durability and flexibility. In the field of coatings, it contributes to the development of protective layers that are resistant to harsh environmental conditions. Additionally, it finds application in the production of rubber and elastomers, improving their thermal stability and resistance to degradation. Its ability to form strong bonds makes it a key component in various industrial processes requiring robust and long-lasting materials.
