SINOMER® MPEGMA 350 (CAS 26915-72-0) is a water-soluble PEG-based methacrylate 单体 manufactured for water-based coatings, inks, and adhesives.
SINOMER® MPEGMA 350
(Water-Soluble Reactive 单体 with High Wetting & 柔韧性)
Chemical Name: Poly(ethylene glycol) (350) methyl ether methacrylate
CAS No.: 26915-72-0
Molecular structure：
SINOMER® MPEGMA 350 is a long-chain methacrylate monoester based on an ethylene oxide backbone, containing approximately 8 ethylene oxide (EO) units . This 功能单体 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 柔韧性 and reduces brittleness in cured films
Reactive 单体 – 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 柔韧性 are required:
20 公斤 or 200kgs/桶
存放于干燥、清洁、通风良好的仓库中.
避免受光照和受热.
运输过程中防止泄漏、雨淋和曝晒.
