TOPLUS® Triethylene Glycol Monobutyl Ether (TB), also known as Butoxytriglycol, is a high-boiling-point, hydrophilic glycol ether characterized by its low volatility, excellent water solubility, and strong coupling ability. As a member of the ethylene oxide-based "E-series" glycol ethers with an extended chain length, it provides unique performance in applications requiring prolonged solvent action, effective coupling of water with polar and non-polar compounds, and enhanced penetration.
The primary value of TB lies in its combination of high boiling point, low vapor pressure, and significant hydrophilicity. Its key applications include serving as a vital coupling agent and solvent in water-based industrial and institutional cleaning formulations, where it effectively bridges water with oils, greases, and hydrophobic functional additives. It is also an important component in water-based coatings, inks, and dye formulations to improve stability and performance. Furthermore, TB is utilized as a key ingredient in hydraulic and brake fluids due to its lubricity and moisture-absorbing properties, and finds specialized use as a penetrant and carrier solvent in agrochemicals and textile processing aids.
The efficacy of TB is determined by critical quality specifications such as high purity, low water content, specific gravity, and a defined distillation range. Consistent high purity ensures predictable performance, compatibility in complex formulations, and reliability in demanding functional applications.
As a producer of high-performance specialty solvents, TOPLUS® supplies premium Triethylene Glycol Monobutyl Ether (TB) to meet the stringent requirements of advanced formulations. TOPLUS® TB is characterized by its consistent high purity, optimal hydrophilic-lipophilic balance, and excellent thermal stability. This ensures reliable performance as a coupling agent in challenging cleaning systems, stable functionality in water-based coatings and hydraulic fluids, and effective delivery in carrier applications. By providing this high-boiling-point, low-volatility solvent, TOPLUS enables formulators in the cleaning, coatings, functional fluids, and chemical processing industries to develop safer, more stable, and higher-performing products.
