Used as a reactive diluent in UV-curable coatings and inks, enhancing flexibility and adhesion properties. Acts as a chain transfer agent in polymerization processes, controlling molecular weight and improving resin performance. Employed in the production of adhesives and sealants to modify rheological characteristics and increase durability. Also utilized in the synthesis of specialty chemicals where thiol functionality is required for crosslinking or modification. Its low odor and efficient reactivity make it suitable for applications in consumer products and industrial formulations.
