Bis-MPA™, or Dimethylol Propionic Acid (DMPA) (CAS: 4767-03-7), is known as a key building block in polyurethane dispersions (PUD) for coatings and adhesives. It can also be used for a wide variety of chemical syntheses.
Waterborne and solvent-free PUDs need to deliver not just low/no volatile organic compounds (VOC) solutions for coatings and adhesives, but stable and precise performance properties within cost requirements.
Perstorp's PUD building blocks, such as Bis-MPA™, Oxymer™, Ymer™ and renewable polyalcohols provide resin producers the ultimate flexibility to choose the exact properties they require being hard to soft, rigid to flexible, but always sustainable.
