PGE-500 (Poly(ethyleneglycol)bis(p-dimethylamino)benzoate) | CAS 71512-90-8

PGE-500 (Poly(ethyleneglycol)bis(p-dimethylamino)benzoate) | CAS 71512-90-8

Product Overview
PGE-500, also known as C130A, is a specialty polymeric photoinitiator co-monomer widely applied in modern UV-curable systems. With excellent solubility, flexibility, and low migration properties, PGE-500 is designed for high-performance coatings, inks, adhesives, and electronic materials. Its unique molecular structure ensures reliable curing performance and compatibility across diverse acrylates and resins.

Key Advantages

• Low Migration – Ideal for food packaging, labels, and other sensitive applications.

• Improved Compatibility – Blends well with a wide range of acrylates and resin systems.

• Enhanced Photoinitiation – Provides a strong synergistic effect when used with Type I photoinitiators.

• Regulatory Compliance – REACH pre-registration and registration support available.

• Reliable Supply – Consistent quality from trusted manufacturing in China.

Applications

• UV-curable coatings (wood, plastic, and metal surfaces)

• UV printing inks for packaging and commercial printing

PGE-500 as a Replacement for EDB (Ethyl-4-dimethylaminobenzoate, CAS 10287-53-3)
One of the key advantages of PGE-500 is its ability to replace traditional small-molecule co-initiators such as EDB (C130). Unlike EDB, which can migrate out of cured films and pose safety concerns in food packaging applications, PGE-500 is a polymeric structure that integrates into the resin system, offering very low migration levels.

In addition, PGE-500 provides:

• Higher photoinitiation efficiency due to synergistic effects with Type I photoinitiators.

• Better compatibility across diverse acrylates and resin systems.

• With REACH, regulatory compliance with stricter international standards.

This makes PGE-500 not only a high-performance alternative to EDB, but also a safer and more sustainable solution for modern UV-curable applications.
