Thermo Scientific™ Ethylene Glycol Dimethacrylate (EGDMA) 98% stabilised is a high-purity bifunctional methacrylate ester widely used as a crosslinking agent in polymer synthesis, advanced materials engineering, resin formulations, surface coatings, and specialty adhesives. Its dual methacrylate functional groups enable efficient network formation, making it essential for producing rigid, durable, and chemically resistant polymer structures.

Stabilised with 90–150 ppm MEHQ (4-methoxyphenol) to prevent premature polymerisation, the reagent retains excellent stability during storage and handling. With a GC purity of ≥97.5%, controlled refractive index, and conformity to infrared identity testing, this material is optimised for demanding laboratory, industrial, and R&D applications.
