Product Detail

Description
DMPA is a molecule that has both hydroxyl and carboxyl groups, unique and multi-functional resistance.DMPA is a multifunctional molecule containing both hydroxyl and carboxyl groups. After neutralization with an alkali, the free carboxylic acid group helps improve the water solubility or water dispersibility of resins.
The introduction of polar functional groups can improve coating adhesion and the dyeability of synthetic fibers, while also increasing the alkali solubility of coating resins. DMPA is suitable for use in waterborne polymer and coating systems.
DMPA is an odorless, free-flowing, white crystalline solid.

Type
2,2-Bis(hydroxymethyl)propionic Acid (DMPA)
