Description

Diethylene Glycol Ethyl tert-Butyl Ether is a high-purity glycol ether solvent with a unique branched alkyl structure. This compound matters for formulators seeking a solvent with excellent solvency power, favorable evaporation rates, and enhanced stability in demanding applications. Industries such as coatings, inks, electronics cleaning, and specialty chemical synthesis need it for its ability to dissolve a wide range of resins and act as a reaction medium or coupling agent.

Application

• Coatings & Inks Formulation: Acts as a coalescing agent and solvent in water-based and solvent-based systems, improving film formation and flow properties.
• Industrial & Electronics Cleaning: Used in precision cleaning formulations for degreasing and removing fluxes due to its solvency and highly volatile nature.
• Chemical Synthesis & Reaction Medium: Serves as an inert, high-boiling solvent for organic synthesis and polymerization reactions.
• Adhesives & Sealants: Functions as a plasticizer and viscosity modifier, enhancing workability and adhesion.
• Agricultural Chemical Adjuvants: Employed as a carrier or penetrant in pesticide and herbicide formulations.
• Metalworking Fluids: Incorporated as a coupling agent and stabilizer in coolants and lubricants.

Quality Control

Our Diethylene Glycol Ethyl tert-Butyl Ether is manufactured under a rigorous quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep container tightly sealed when not in use to prevent evaporation and moisture pickup.
