Used as a reactive diluent and crosslinking agent in epoxy resin systems. Enhances flexibility and impact resistance of coatings, adhesives, and composites. The ester group and oxirane ring allow it to participate in curing reactions, improving adhesion to various substrates. Commonly applied in UV-curable formulations and specialty polymers where low viscosity and good reactivity are required. Also utilized in the synthesis of biodegradable polymers due to its aliphatic chain and functional reactivity.
