Features Of Triethylene Glycol Butyl Ether TBG

  1. Excellent solvency for resins, cellulose esters, and acrylic polymers.

  2. Low volatility and high boiling point (≈ 275 °C), supporting extended wet-film time in coatings.

  3. Good water miscibility and coalescing performance in waterborne systems.

  4. Low skin irritation potential and favorable toxicological profile versus shorter-chain glycol ethers.

  5. Effective coupling agent for stabilizing heterogeneous formulations in industrial cleaners and inks.

Typical Applications Of Triethylene Glycol Butyl Ether TBG

  1. Coalescing agent in architectural and industrial water-based acrylic and vinyl acetate emulsion paints.

  2. Solvent and viscosity reducer in high-solids coil coatings and automotive refinish systems.

  3. Carrier solvent in agricultural adjuvants and pesticide formulations requiring low volatility and good leaf retention.

  4. Performance enhancer in aqueous inkjet inks for improved jetting stability and substrate penetration.

  5. Key ingredient in heavy-duty industrial cleaners for removing greases, waxes, and polymer residues.
