Dibasic ester

Dibasic ester (CAS 95481-62-2), commonly referred to as DBE or marketed under the trade name Estasol, is a blend of dimethyl esters of succinic, glutaric, and adipic acids.

Where is Dibasic ester used?

• Industrial coatings and paint strippers: coalescing solvent and active stripping agent that dissolves cured resins and reduces VOC content
• Adhesives and sealants: plasticizer improving flexibility and substrate adhesion in polyurethane and epoxy systems
• Plastics processing: processing aid and plasticizer for PVC and other polymer compounds where controlled softening is required
• Metalworking fluids: carrier solvent and cleaner base
• It is used as a high-boiling solvent and plasticizer across industrial manufacturing.
• Intermediate in the production of specialty chemicals.
• Base binder for casting.
• Printing ink industry.
• Can replace glycol ethers, usually in blends with other solvents.

Good to know: Its low volatility, strong solvency and high flash point make it a practical alternative to conventional solvents in demanding coating and polymer applications, supporting safer handling.

Formulation notes

• Blends of 70% to 80% dibasic ester and 30% to 20% NMP are recommended as more effective than either solvent alone.

Typical specification

• Water content maximum 0.1 wt%.
• Typical composition: 59% dimethyl glutarate, 20% dimethyl succinate, and 21% dimethyl adipate.
• Available in both purified and mixed grades of adipic, glutaric, and succinic esters.
• Color maximum 15 APHA.

Regulatory status

• Not classified as hazardous under Regulation (EC) 1272/2008 (CLP).
• Not subject to any special transport regulations.

Storage, packaging and handling

• Non-reactive and chemically stable when stored as intended.
• Supplied in drums and IBCs.

Frequently asked questions about Dibasic ester

Which resins and polymers can a dibasic ester formulation dissolve?
