SINOMER® MPEGMA 350

(Water-Soluble Reactive Monomer with High Wetting & Flexibility)

Chemical Name:  Poly(ethylene glycol) (350) methyl ether methacrylate

CAS No.:    26915-72-0

Molecular structure

General information :

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.

Properties :
  • 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 

Applications :

SINOMER® MPEGMA 350 is widely used in various coating, ink, and adhesive formulations where water solubility, wetting, and flexibility are required:

Coatings

Water-based automotive coatings, alkyd dispersions, polyurethane dispersions (PUDs), water-based industrial coatings 

Inks

Water-based inks, pigment dispersions, colorant concentrates 

Adhesives

Anaerobic adhesives, water-based pressure sensitive adhesives (PSAs), laminating adhesives 

Specialty Applications

Soil stabilizing hydrogels, flocculating agents, surface modification for antifouling materials, polyether sulfone (UF) membrane modification 

Polymer Synthesis

Reactive diluent for radiation-curable systems, macromonomer for graft copolymers, intermediate for polycarboxylate superplasticizers 


Packaging :

20kg or 200kgs/Drum

Storage :
