Benzyl glycidyl ether

Benzyl glycidyl ether (CAS 2930-05-4) is a reactive epoxy monomer used to modify and extend epoxy resin systems.

Where is Benzyl glycidyl ether used?

• Electronics: encapsulants and underfill compounds requiring controlled flow and low viscosity before cure
• Structural adhesives and sealants for automotive and aerospace assemblies: improved processability
• High-solids and solvent-reduced epoxy coatings: viscosity targets for industrial spray or brush application
• Specialty polymer synthesis: building block where a pendant benzyloxy group is required
• As a reactive diluent it reduces viscosity in uncured formulations.

Good to know: It incorporates into the cured polymer network rather than remaining as a free plasticizer, allowing better application without sacrificing crosslink density in the final bond.

Commercial specifications

• Purity typically 98% or higher, confirmed by GC analysis
• Drum and IBC quantities
