Used primarily as a reactive monomer in the synthesis of specialty polymers and resins. Its rigid tricyclic structure contributes to high thermal stability and mechanical strength in the resulting materials. Commonly employed in coatings, adhesives, and electronic encapsulants where durability and resistance to heat are required. Also utilized in photo-curable systems due to its ability to undergo rapid polymerization under UV light, making it suitable for inks, dental materials, and 3D printing resins. The (E)-isomer offers better structural regularity, enhancing crosslinking efficiency and final product performance.
