Isobornyl Methacrylate is a methacrylate monomer carrying an isobornyl group, a bulky bicyclic framework derived from camphor. The product is supplied stabilized with MEHQ, a polymerization inhibitor added so that the monomer does not undergo spontaneous polymerization during storage and transport. In the laboratory, this monomer is used as a building block for acrylate copolymers and as a component in resin formulations that cure through a free-radical mechanism, whether initiated thermally or by ultraviolet irradiation.

The large, rigid isobornyl group is the main reason this monomer is selected. That bicyclic structure restricts polymer chain mobility, so the resulting polymers tend to show a high glass transition temperature, good surface hardness, and hydrophobic character that contributes to water resistance. The monomer is also known for giving relatively low volume shrinkage during curing compared with short-chain acrylate monomers, an important advantage in coatings and adhesives that demand dimensional stability. These properties make it a frequent choice for balancing hardness and flexibility within a formulation.

In Indonesian laboratories, this material is typically handled in polymer chemistry, materials science, and coatings research groups at universities and industrial R&D units. It is commonly used at bench scale for preparing trial copolymer batches, screening initiator systems, and evaluating cured film properties before a formulation is scaled up. Because it is a reactive monomer supplied with an inhibitor, it is generally ordered in quantities matched to the planned experimental programme rather than stored for long periods.

  • Acrylate copolymer synthesis: serves as a rigid comonomer whose bicyclic isobornyl group raises the glass transition temperature of the resulting copolymer in a controlled way.
  • UV-curable coating formulation: participates in free-radical photopolymerization under ultraviolet irradiation, contributing surface hardness and hydrophobicity to the cured film without adding excessive shrinkage.
  • Thermally initiated resin preparation: cures through free-radical mechanisms with thermal initiators, making it suitable for bench studies of resin systems that are processed by heating rather than by light.
  • Adhesive formulation studies: its relatively low volume shrinkage during curing supports dimensional stability, a property that matters when evaluating bond integrity in adhesive research work.
  • Hardness and flexibility balancing: used as an adjustable formulation component in which the proportion of the bulky isobornyl monomer tunes the stiffness of the final polymer network.

Storage keep the inhibitor intact by storing under the conditions stated on the manufacturer's label
  • Product code: I0617
  • Form: liquid methacrylate monomer, supplied stabilized with MEHQ

Store the monomer in a cool place away from direct sunlight, heat sources, and any source of ignition, following the conditions stated on the manufacturer's label. Keep the container tightly closed in its original packaging or in a compatible chemically resistant bottle, since the MEHQ inhibitor is what prevents spontaneous polymerization during storage. Do not remove or exhaust the inhibitor unnecessarily, and avoid prolonged storage at elevated temperature. Handle the material in a well-ventilated area or fume hood, wear chemical-resistant gloves, safety goggles, and a laboratory coat, and avoid skin and eye contact as well as inhalation of vapours. Dispose of residues and contaminated materials in accordance with applicable laboratory chemical waste procedures.
