Bisomer® MPEG550MA - Technical Datasheet
Applications
Bisomer® MPEG550MA is water soluble and contains approximately 12 ethylene oxide (EO) units in the
chain. It is an excellent material to impart water solubility or water dispersibility into non-ionic organic
molecules. It is also an excellent flexibilising molecule due to its low Glass Transition Temperature (Tg).
Bisomer® MPEG550MA is ideal in water-based automotive coatings, alkyd dispersions, polyurethane
dispersions (PUDs), soil stabilising hydrogels, flocculating agents, anaerobic adhesives and water-based
pressure sensitive adhesives (PSAs).
Bisomer® MPEG550MA is non-toxic and a liquid at ambient temperature.
Transportation, Handling & Storage
Please refer to the safety datasheet for details.
Shelflife: When kept in original closed containers under the storage conditions recommended in the SDS,
Bisomer® MPEG550MA is stable for at least 3 years.
