Isobornyl Methacrylate (IBOMA) is a rigid, bicyclic monofunctional methacrylate monomer and low-viscosity reactive diluent. Its bulky isobornyl group gives cured polymers a high glass-transition temperature (Tg ≈ 110 °C) with hardness, scratch resistance, weatherability, and strong hydrophobicity, while lowering acrylic-resin solution viscosity without sacrificing solids or Tg. Compared with the acrylate IBOA, IBOMA cures more slowly but delivers higher Tg and a milder hazard profile — it is not a skin sensitiser. Royalchem Spain supplies bio-based (camphene-derived) IBOMA at ≥ 99.5% purity, stabilised with MEHQ and a drop-in equivalent to grades such as SR423 / Sipomer IBOMA, delivered from our Valladolid hub by drum, IBC, or ISO tank.

Reactive diluent and co-monomer that cuts solution viscosity for low-VOC, high-solid acrylic coatings while holding Tg and hardness. Used in automotive clearcoats, wood and plastic finishes, industrial, marine and architectural coatings, and electronics conformal coatings.
Tackifier and cohesion / hardness booster in pressure-sensitive and structural adhesives, with good adhesion to low-surface-energy plastics. Used in industrial tapes, optical adhesives, and assembly adhesives.
Melt-flow and leveling improver that enhances powder stability, gloss, and surface appearance, and produces high-Tg thermoplastic acrylic resins. Also used as a low-shrinkage viscosity modifier in dental and optical resins.
Standard Packaging:
200 kg HDPE or lined steel drums, IBC totes (approx. 1000 kg), or ISO tank for bulk. Distributed by Royalchem Spain from our Valladolid hub. Shelf life 6 – 12 months in original sealed packaging.
Storage Conditions:
Store sealed in a cool (below 30 °C), dry, dark place, away from heat, sparks, oxidising agents, peroxides, and other radical sources. Do not blanket with nitrogen or inert gas — the MEHQ inhibitor requires dissolved oxygen, so a normal air headspace must be maintained to prevent premature polymerisation.
