2. Overview of Isobornyl (Meth)acrylate (IBOA/IBOMA ) Identifications, Properties and Applications Isobornyl methacrylate is made from Camphene , a natural product f rom pine trees. It is a colorless transparent liquid used as a monomer in polymer production. It acts as a reactive solvent with low vapor pressure, facilitating free radical polymerization to form polymers with high glass transition temperatures. IBOMA is used in applications requiring both rigidity and durability, such as in coatings, adhesives, and optical films. It meets regulatory standards for use in plastic articles intended for food.
