Diethylene glycol monobutyl ether

CAS: 112-34-5

Overview

Diethylene glycol monobutyl ether (CAS 112-34-5 ), also known commercially as DGBE or butyl DGBE, is a slow-evaporating glycol ether solvent used across coatings, cleaning, and ink formulations.

Its controlled evaporation rate and compatibility with both water and organic systems make it a practical choice for formulators managing film formation and solvent balance in various applications.

In architectural and industrial coatings, it functions as a coalescing agent and coupling solvent, improving film formation in waterborne systems and preventing surface defects during drying.

Printing ink manufacturers incorporate it to control viscosity and drying speed in gravure and flexographic formulations, particularly where open time needs to be extended for better results.

In industrial and institutional cleaning products, it acts as a degreasing solvent and emulsifier, helping to lift oils and soils from hard surfaces while keeping the formulation stable.

Adhesive and sealant producers use it as a carrier solvent to aid dispersion of resins and improve substrate wetting before cure, ensuring a high-quality bond across different materials.

The product is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume buyers. Standard supply grades include technical and industrial purity.

Material typically meets a 99% minimum purity level. Specifications are aligned with common industry standards, and certificates of analysis are standard for quality-controlled procurement.
