2-isocyanatoethyl acrylate

2-Isocyanatoethyl acrylate (CAS 13641-96-8) is a bifunctional reactive monomer combining an isocyanate group and an acrylate group within a single molecule.

Where is 2-isocyanatoethyl acrylate used?

• UV-curable coatings and inks: crosslinking monomer that builds urethane linkages, improving adhesion, hardness and chemical resistance in the cured film
• Adhesives and sealants: modifies acrylate backbones with isocyanate functionality for moisture-cure or dual-cure bonding systems
• Acrylic resins: introduces pendant isocyanate groups for post-functionalization and reactive blending with hydroxyl-bearing or amine-bearing substrates
• Printing and packaging: supports high-performance overprint varnishes
• In laminating adhesives it serves where flexibility and high crosslink density are critical.

Good to know: Stabilized liquid monomer; premature polymerization must be prevented during storage and transport.

Commercial specifications

• Purity commonly 97% or higher
• Packaging from laboratory quantities to drum scale
