A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Bisphenol A diglycidyl ether epoxy resin (CAS 25068-38-6), the bisphenol-A-based liquid epoxy that is the building block of most epoxy systems. It is used to formulate adhesives, protective and industrial coatings, castings and pottings, and fiberglass-reinforced composite laminates. Cured DGEBA epoxies are valued for adhesion and chemical resistance.

Frequently Asked Questions
Is DGEBA liquid epoxy resin an equivalent to Epon 828?
DGEBA liquid epoxy resin is the generic liquid bisphenol-A diglycidyl ether (DGEBA) epoxy resin commonly sold as Epon 828. RawSource supplies an independent equivalent — verified to your specification and Certificate of Analysis — and is not affiliated with, authorized by, or endorsed by Hexion.
What is bisphenol A diglycidyl ether (DGEBA) used for?
Bisphenol A diglycidyl ether epoxy resin (CAS 25068-38-6) is the bisphenol-A-based liquid epoxy that is the building block of most epoxy systems. It is used to formulate adhesives, protective and industrial coatings, castings and pottings, and fiberglass-reinforced composite laminates, valued for adhesion and chemical resistance after cure.
Who supplies bisphenol A diglycidyl ether in bulk?
RawSource supplies DGEBA epoxy resin (CAS 25068-38-6) in bulk to adhesive, coating, casting, and composite manufacturers. Request a bulk quote with your target volume, viscosity/epoxy-equivalent requirement, and destination.
What is the CAS number and HS code for DGEBA epoxy resin?
DGEBA liquid epoxy resin is CAS 25068-38-6 and classifies under HS 3907.30 (epoxide resins). The single-monomer BADGE has its own CAS (1675-54-3); confirm which form your specification requires on the quote.
What is BADGE and how does it relate to DGEBA resin?
BADGE is bisphenol A diglycidyl ether, the pure diglycidyl ether monomer. Commercial DGEBA liquid epoxy (CAS 25068-38-6) is the oligomeric resin built on that BADGE backbone and is the standard base for most epoxy formulations.
How is DGEBA epoxy resin packaged and can you provide a CoA and SDS?
We supply DGEBA epoxy resin in bulk packaging such as pails, drums, and totes, with packaging and MOQ confirmed per order. A Certificate of Analysis (including epoxy equivalent weight and viscosity) and a Safety Data Sheet are available with each shipment; request a bulk quote with your target volume.
What is the REACH and TSCA regulatory status of DGEBA Liquid Epoxy Resin (Bisphenol-A Diglycidyl Ether)?
DGEBA Liquid Epoxy Resin (Bisphenol-A Diglycidyl Ether) (CAS 25068-38-6) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 500-033-5).
