DMPA is the industry-standard hydrophilic chain extender for waterborne systems:

• Waterborne Polyurethanes (PUD):
  Introduces carboxyl groups into the polyurethane backbone, enabling water dispersibility after neutralization with amines (e.g., TEA). Essential for eco-friendly coatings, leather finishes, and adhesives.

• Water-Soluble Alkyds & Polyesters:
  Modifies resin structures to impart water solubility without sacrificing hardness or gloss.

• Electrodeposition Coatings:
  Used in anodic electrodeposition systems as an anionic dispersing monomer.

Packaging: 25kg Multi-ply Paper Bag (PE lined) / 500kg Supersack.

Storage: Hygroscopic material. Store in tightly sealed containers in a dry area to prevent clumping.
