1,2-Propylene Diacetate (CAS 623-84-7), commercially abbreviated as PDA or PGDA, is a clear, colorless liquid ester produced via the acetylation of propylene glycol, primarily utilized as a highly efficient hardener in foundry resins and a low-toxicity solvent in industrial inks. This Propylene glycol diacetate compound functions as a latent curing agent in 1,2-Diacetoxypropane based phenolic urethane systems, regulating the setting time of sand molds through controlled hydrolysis, while also serving as a slow-evaporating solvent for screen printing inks requiring extended open times. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

FAQ - Technical & Supply Chain
-
Q:
Is 1,2-Propylene Diacetate (CAS 623-84-7) a direct replacement for Triacetin?
A: While both are ester-based hardeners (C7H12O4 vs C9H14O6）, PDA typically offers a faster curing rate than Triacetin in foundry binder systems, allowing for adjustable reactivity when used in blends. -
Q:
What is the primary advantage of using PDA in ink formulations?
A: It acts as a strong solvent with a high boiling point and low volatility, which prevents the ink from drying on the screen mesh during printing operations while maintaining excellent flow properties.
