Description

Diethyleneglycol Methyl-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, low volatility, and favorable environmental and toxicological profiles compared to traditional options. It is primarily needed by manufacturers in the coatings, inks, and industrial cleaning sectors, where it acts as a coalescing agent and active solvent.

Application

• As a coalescing aid and solvent in water-based architectural and industrial coatings.
• As a solvent and flow promoter in printing inks, particularly for flexographic and gravure applications.
• As a key component in industrial and institutional cleaning formulations, including hard surface cleaners and degreasers.
• As a chemical intermediate in the synthesis of specialty polymers and surfactants.
• As a processing solvent in the manufacture of agrochemicals and pharmaceutical products.
• As a component in brake fluid formulations and other functional fluids requiring high boiling points and stability.
