1,4-Butanediol diglycidyl ether (BDDE) is a difunctional glycidyl ether used as a reactive diluent, epoxy modifier, and crosslinking agent in polymer formulations. Its two epoxide groups enable reaction with compatible curing agents, functional polymers, and hydroxyl- or amine-containing materials.
Synonyms: BDDE; 1,4-Butane diglycidyl ether; 1,4-Diglycidyloxybutane; 1,4-Bis(glycidyloxy)butane; Tetramethylene glycol diglycidyl ether.
BDDE is commonly used in epoxy resins, adhesives, sealants, coatings, composites, and hydrogel research where flexibility, crosslink density, viscosity reduction, or network formation are important formulation targets. The product listing notes a WPE of approximately 130.

Applications
Epoxy Resin Modification
1,4-Butanediol diglycidyl ether is used as a reactive diluent in epoxy resin systems to help adjust viscosity, flexibility, and cured material properties.
Coatings & Composites
BDDE may be incorporated into epoxy-based coatings and composite formulations where toughness, adhesion, chemical resistance, and processing behavior are key performance factors.
Adhesives & Sealants
Used in epoxy adhesive and sealant systems to support crosslinking, flexibility, and bond performance in compatible formulations.
Hydrogel & Polymer Crosslinking Research
BDDE is used in research involving crosslinked polymer networks and hydrogels, including systems based on hydroxyl-containing polymers such as polysaccharides.
Preparation & Use Considerations
- Confirm compatibility with selected resins, curing agents, catalysts, solvents, and functional polymers
- Crosslink density and final material properties depend on formulation ratio, cure conditions, polymer structure, and processing method
- Epoxy equivalent weight, viscosity, and cure response should be evaluated within the intended formulation
- Perform application-specific testing before scale-up or production use
Handling & Storage
- Store tightly sealed in a cool, dry, well-ventilated area
- Protect from heat, ignition sources, moisture, and incompatible materials
- Use appropriate gloves, eye protection, and ventilation
- Avoid skin contact with epoxy reactive diluents and uncured epoxy formulations
- Refer to the Safety Data Sheet for complete handling, storage, and disposal guidance
