Product Information

DMPA® Dimethylolpropionic Acid is a unique and versatile hindered diol molecule with both hydroxyl and carboxyl functionality. The neopentyl structure of this trifunctional compound, having two primary hydroxyl groups and one tertiary carboxylic group, permits simplified processing by allowing the combining of all reactants in a single kettle charge. Good control of the reaction is possible due to the slower esterification rate of the tertiary carboxyl, assuring a uniform distribution of carboxyl groups along the resin backbone. The free acid group actively promotes resin water solubility or water dispersibility after neutralization with a base, easily introduces a polar group to improve coating adhesion and synthetic fiber dye receptivity, and increases the alkali solubility of deposited films. DMPA® is an odorless, free flowing white crystalline solid, which provides superior advantages in the formulation and processing of water soluble resins.
