Polyethylene Glycol Diacrylate (PEGDA)

1. Product Overview

Polyethylene Glycol Diacrylate (PEGDA) is a high-performance, UV-curable oligomer widely used in polymer synthesis and advanced material engineering. It serves as a crosslinking agent that enables the formation of hydrogels, coatings, and photo-reactive systems with precise mechanical and chemical properties. Its key value proposition lies in its tunable molecular weight, excellent biocompatibility, and rapid curing capabilities under UV or electron beam exposure. Strategically, PEGDA is critical in industries such as biomedical engineering, 3D printing, and specialty coatings, where precision, scalability, and performance consistency are essential.
