What is Dibasic Esters DBE CAS 95481-62-2?

DBE is a commercial mixture of dimethyl esters of adipic, glutaric and succinic acids, not a single fixed molecule. A standard DBE blend typically contains about 55-65% dimethyl glutarate, 15-25% dimethyl succinate and 10-25% dimethyl adipate, with individual CAS numbers 1119-40-0, 106-65-0 and 627-93-0.

Which physical properties and specifications are typical for DBE?

Compare ester composition, total ester content, water, color, acid value and distillation range. Typical DBE is a clear, colorless to pale yellow liquid with density about 1.06-1.09 g/cm³, boiling range about 196-225 °C, flash point about 100 °C and low vapor pressure.

What is Dibasic Esters used for?

DBE is used as a high-boiling, slow-evaporating mixed ester solvent and leveling agent in coatings and inks, including automotive OEM, coil, baking and plastic coatings. It is also used as a reactive diluent in polyurethane systems, and in industrial cleaners, paint strippers and metalworking fluids.

Why is DBE described as an environmentally preferred solvent?

DBE is promoted as a lower-odor, high-flash, slow-evaporating alternative to some aromatic hydrocarbons, ketones and glycol ethers in cleaning and coating applications. Environmental and VOC status still depends on the grade, formulation and destination regulation, so the specific DBE blend should be confirmed.

How should DBE be stored and handled?

DBE is combustible and should be stored in tightly closed, compatible containers in a cool, dry, ventilated area away from heat, sparks and open flames. Avoid moisture ingress and contamination, and use chemical-resistant gloves and eye protection during transfer.
