Import Dmpa 4767-03-7 — Buy in Bulk from Supplier in China

Dmpa 4767-03-7, or 2,2-Dimethylol Propionic Acid, is a white crystalline solid with a molecular formula of C5H10O4 and a molecular weight of 134.13 g/mol. It is supplied as a powder with a purity of at least 99.0% by HPLC, as stated in the product documentation. The compound has a melting point between 155°C and 159°C and exhibits high solubility in water and polar organic solvents, making it suitable for aqueous formulations.

This compound functions primarily as a hydroxyl-containing chain extender in polyurethane dispersions and waterborne coatings. It is commonly used in industrial applications where low-VOC formulations are required, such as in architectural paints, wood finishes, and textile binders. The carboxylic acid group enables ionic stabilization of polymer particles, while the two hydroxyl groups allow crosslinking with isocyanates. Standard industry practice requires the acid value to be between 380 and 420 mg KOH/g, which this material meets.

Buyers typically source Dmpa 4767-03-7 for use in waterborne resin systems, especially in regions with strict environmental regulations.
