What is 1,4-butanediol diglycidyl ether?
1,4-Butanediol diglycidyl ether (CAS 2425-79-8), commonly abbreviated as BDDGE, is a bifunctional epoxy reactive diluent and crosslinker.
Where is 1,4-butanediol diglycidyl ether used?
- Epoxy coatings and flooring: lowers formulation viscosity without sacrificing cure performance
- Adhesives and sealants: reactive diluent that extends pot life and improves flexibility in cured bond lines
- Polymer and elastomer production: crosslinking agent for hydroxyl- or amine-terminated systems, including hydrogels and surface-modified materials
- Printing inks: adjusts flow properties in UV-curable and solvent-based systems
- It reduces viscosity in epoxy formulations while contributing to the final crosslink density of the cured network.
Commercial specifications
- Standard commercial grades at purities of 95% and above
- Technical and high-purity grades offered
- Packaging from drums to IBC containers
