Ethylene Glycol Mono-tert-butyl Ether (ETB, CAS 7580-85-0), also known as tert-butyl ethylene glycol, is a versatile organic solvent distinguished by its low volatility, high solvency, and low toxicity. It is widely used in coatings, adhesives, inks, and cleaning formulations, offering an eco-friendly solution for industries focused on sustainability and efficiency.
ETB is a colorless liquid with a mild, pleasant odor, prized for its excellent ability to dissolve resins and polymers, along with its compatibility with both water and organic solvents. With a boiling point of about 152°C and a flash point of 47°C (closed cup), it combines safety with strong performance, making it suitable for a broad range of industrial applications.
