Product Name	Poly(ethylene glycol) bis(p-dimethylaminobenzoate) (PGE-500 / Polymeric Amine Synergist ASA)
CAS NO.	71512-90-8
Formula & Weight	C22H28N2O5 · (C2H4O)n (Mn ≈ 500-520 g/mol)
Chemical Structure
Technical Specifications	Appearance: Yellowish to brownish viscous liquid Active Content: ≥ 98.0% Viscosity (25°C): 1000 - 2000 mPa.s Residual EDB: ≤ 500 ppm (Low Impurity) Acid Value: ≤ 1.0 mg KOH/g Solubility: Fully soluble in common UV monomers and oligomers.
Why Use PGE-500?	The solution for Low Migration & Low Odor: Low Migration: Due to its polymeric structure (high molecular weight), it has minimal migration potential, making it ideal for food packaging (FCM) and sensitive applications. High Reactivity: Acts as a highly efficient amine synergist, accelerating surface cure and overcoming oxygen inhibition as effectively as EDB/EHA. Low Odor & Low Volatility: Significantly reduces the residual odor in the final cured product compared to small-molecule amines. Applications: UV food packaging inks, UV varnishes for toys, and low-odor wood coatings.
Packaging & Storage	Packaging: 25kg Plastic Drum or 200kg Iron Drum. Storage: Store in a cool, dry area away from light. Shelf life is 24 months under proper conditions.
