What is Diethylene glycol monobutyl ether?
Diethylene glycol monobutyl ether (CAS 112-34-5), also known commercially as DGBE or butyl DGBE, is a slow-evaporating glycol ether solvent.
Where is Diethylene glycol monobutyl ether used?
- Coatings: coalescing agent and coupling solvent, improving film formation in waterborne systems and preventing surface defects during drying
- Printing inks: viscosity and drying-speed control in gravure and flexographic formulations
- Cleaning products: degreasing solvent and emulsifier that lifts oils and soils from hard surfaces
- Adhesives and sealants: carrier solvent aiding resin dispersion and substrate wetting before cure
- It controls evaporation rate and is compatible with water and organic systems.
Commercial specifications
- 99% minimum purity
- Clear liquid in drums, IBCs and bulk tankers
- Certificates of analysis standard for quality-controlled procurement
