What is 2-ethylhexyl methacrylate?
2-Ethylhexyl methacrylate (CAS 688-84-6), commonly abbreviated as 2-EHMA, is a long-chain acrylic monomer used to modify the flexibility, adhesion, and glass transition temperature of polymer systems.
Where is 2-ethylhexyl methacrylate used?
- Coatings and printing inks: copolymerized to improve film flexibility and substrate adhesion, particularly on flexible packaging substrates
- Adhesives: incorporated into pressure-sensitive and structural systems where low-temperature performance and tack balance are critical
- Personal care: film-forming polymer systems for nail coatings and hair fixatives
- Plastics: reactive softening comonomer that reduces brittleness in acrylic-based materials without sacrificing clarity or processability
- It functions as a reactive building block in emulsion and solution polymerization.
Commercial specifications
- Inhibitor such as MEHQ added for storage stability
- Purity specifications commonly at 98% or higher
- Bulk supply in drums and IBC containers
