Used as a hydrophobic monomer in polymer synthesis, particularly in specialty coatings and resins where moisture resistance and flexibility are required. Its spirocyclic structure contributes to thermal stability, making it suitable for high-performance materials in electronics and aerospace applications. Also employed as a reactive diluent in UV-curable formulations to reduce viscosity without compromising curing efficiency. The ether and acetal functionalities allow for controlled hydrolysis, enabling use in stimuli-responsive polymers and drug delivery systems.
