Frequently Asked Questions

What is 1,4-butanediol diglycidyl ether used for?

It is an aliphatic difunctional epoxy reactive diluent (CAS 2425-79-8) added to epoxy resin systems to reduce viscosity. It also acts as a flexibilizer for aromatic epoxy resins and contributes to network cure through its two epoxide groups.

What is another name for 1,4-butanediol diglycidyl ether?

It is commonly abbreviated BDDGE and referred to as a butanediol-based epoxy reactive diluent. It should not be confused with 1,4-butanediol itself, which is the parent diol; specify CAS 2425-79-8 when ordering.

How does BDDGE function as a reactive diluent?

Because it is difunctional, it lowers the viscosity of an epoxy formulation while still participating in the cure, crosslinking into the resin network rather than remaining inert. It additionally flexibilizes aromatic epoxy systems.

How is 1,4-butanediol diglycidyl ether shipped?

It is assigned UN 3334 and classified under HS 2910.90 (epoxides with a three-membered ring). Transport must follow the requirements applicable to the UN number; consult the SDS and your carrier for classification details.

What is the bulk price and is it available for sale in drums or totes?

It is available in bulk packaging (drums/totes/IBCs) with a CoA and SDS. Pricing depends on volume and packaging; submit a bulk RFQ with your required quantity for a current quote.
