What is Dipropylene glycol dibenzoate?
Dipropylene glycol dibenzoate (CAS 27138-31-4), commonly abbreviated as DPGDB, is a benzoate ester plasticizer and coalescing solvent used in polymer-based formulations and industrial coatings.
Where is Dipropylene glycol dibenzoate used?
- Coatings and adhesives: coalescing agent that lowers minimum film formation temperature for uniform film development in waterborne systems
- Adhesives and sealants: improves tack, flexibility and substrate adhesion in pressure-sensitive and construction-grade products
- PVC and polymer compounding: secondary plasticizer that enhances processing and reduces brittleness in finished parts
- Printing inks: solvent-carrier controlling viscosity and improving pigment wetting in solvent-borne and UV-curable systems
- It also acts as a rheology modifier, improving film formation, flow and flexibility.
Commercial specifications
- Packaging from drums to IBC totes, bulk quantities for large-scale procurement
