FAQ - Technical & Supply Chain
-
Q:
Is this Ethylene Glycol Tert-Butyl Ether (CAS 7580-85-0) distinct from standard Butyl Cellosolve (EGBE)?
A: Yes, this substance contains a tertiary butyl group (C6H14O2) rather than a normal butyl group, which imparts different solubility characteristics and a more favorable toxicological profile for specific industrial formulations. -
Q:
What is the primary utility of ETB in water-based coating systems?
A: It serves as a coalescing solvent and coupling agent that helps emulsify organic resins into the aqueous phase, ensuring uniform film formation during the drying process.
