![]()
SINOMER® MPEGMA 350 is a long-chain methacrylate monoester based on an ethylene oxide backbone, containing approximately 8 ethylene oxide (EO) units . This functional monomer combines a polymerizable methacrylate group with a hydrophilic PEG chain, offering excellent water solubility and compatibility with various resin systems. It is manufactured using advanced esterification technology to achieve high esterification rate (≥93%) and low residual acid content , ensuring consistent performance in demanding applications.

High wetting ability – PEG chain provides excellent substrate wetting and penetration
Water soluble – Imparts water solubility or dispersibility to non-ionic organic molecules
Flexibilizing effect – Low glass transition temperature (Tg) enhances flexibility and reduces brittleness in cured films
Reactive monomer – Methacrylate group enables copolymerization with acrylic, urethane, and other vinyl systems
Low residual acid – Minimizes side reactions and ensures formulation stability
SINOMER® MPEGMA 350 is widely used in various coating, ink, and adhesive formulations where water solubility, wetting, and flexibility are required:
