Introduction
C9H12O2
Propylene glycol phenyl ether can be used as an excellent high-boiling organic solvent or modification aid, replacing isophorone, cyclohexanone, DBE, benzyl alcohol, ethylene glycol phenyl ether series with higher toxicity or odor. Because of its non-toxicity, good miscibility, moderate volatility, excellent polymerization and coupling ability, low surface tension, it is widely used in automotive and automotive refinishing coatings, electrophoretic coatings, industrial baking paints and ship, container and wood coatings.
Introduction to Propylene Glycol Phenyl Ether (PPH)
Propylene glycol phenyl ether (CAS 770-35-4) is a high-boiling, glycol ether solvent with low volatility and excellent solvency for resins, dyes, and coatings. It is widely used in industrial and consumer applications due to its mild odor, slow evaporation rate, and compatibility with polar/non-polar systems.
