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. It is used as a high-boiling solvent and plasticizer across industrial manufacturing.

Its low volatility and strong solvency make it a practical alternative to conventional solvents in demanding coating and polymer applications. In industrial coatings and paint strippers, DBE functions as a coalescing solvent and active stripping agent.

It effectively dissolves cured resins and reduces VOC content in formulations. Adhesive and sealant manufacturers incorporate it as a plasticizer to improve flexibility and substrate adhesion in polyurethane and epoxy systems.

In plastics processing, it acts as a processing aid and plasticizer for PVC and other polymer compounds where controlled softening is required. Metalworking fluid formulators use DBE as a carrier solvent and cleaner base.

Its high flash point supports safer handling in industrial environments. Dibasic ester is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for large-volume procurement.

It is typically offered in technical grade, with specifications aligned to industrial solvent standards covering ester content, water content, and acid value. Some suppliers offer refined grades with tighter purity controls.

These refined grades are suitable for sensitive coating or polymer applications. The material is managed according to standard industrial safety protocols to ensure consistent performance and reliability in diverse manufacturing sectors.
