Used primarily as a monomer in the production of high-performance polyesters and copolyesters, it enhances clarity, thermal stability, and impact resistance in plastics. Its rigid cycloaliphatic structure contributes to improved glass transition temperatures, making it valuable in engineering resins for packaging, automotive components, and electronic materials. It also serves as a building block in UV-curable coatings and adhesives due to its ability to support crosslinking and durability. In specialty applications, it is used in optical materials and medical devices where transparency and biocompatibility are required.
