Isobornyl methacrylate (IBOMA) is an acrylic ester monomer with a bridged-ring structure. Its double bond is a C=C bond, with the methyl group attached to the carbon adjacent to the carbonyl group. Typically, the polymerization rate of methacrylates is slower than that of acrylates because the additional methyl group impedes rotation around the double bond and affects overall reactivity. Compared to IBOA, IBOMA may have a higher viscosity, affecting the ease of preparation process.
Due to its molecular structure characteristics of IBOMA, the polymer has excellent high light, vividness, abrasion resistance, medium resistance and weather resistance, and its moisture absorption is significantly lower than MMA (methyl methacrylate). In addition, acrylic resin added with IBOMA has a good compatibility with polyester, alkyd and many volatile paint film forming substances.
