What is Isobornyl methacrylate?
Isobornyl methacrylate (CAS 7534-94-3), commercially known as IBOMA, is a specialty acrylic monomer used to modify the performance characteristics of UV-curable and thermoplastic polymer systems. Also marketed as Ageflex IBOMA and NK Ester IB.
Where is Isobornyl methacrylate used?
- UV-curable inks and coatings for printing and packaging: reactive diluent that reduces viscosity
- Nail gel and UV-cured cosmetic coatings: durable, high-gloss films with controlled flexibility
- Adhesives and sealants: improved substrate adhesion
- Optical and electronic components: specialty resins where dimensional stability and low shrinkage during polymerization are critical
- It adjusts hardness, adhesion, and shrinkage in polymerizable formulations without compromising cure speed or film integrity.
Commercial specifications
- Purity specifications commonly at 98% or higher for most industrial uses
- Drum and IBC quantities, with bulk tanker supply available from major producers
