Product Introduction
DMPA It is a unique, multifunctional hindered diol molecule with both hydroxyl and carboxyl groups. After the free acid group is neutralized with alkali, it can actively improve the water solubility or water dispersibility of the resin; introduce polar groups to improve the adhesion of paint and the dyeing performance of synthetic fibers; increase the alkali solubility of the coating. It can be used in water-soluble polyurethane systems, water-soluble alkyd and polyester resins, epoxy ester coatings, polyurethane elastomers, and powder coatings. DMPA is an odorless, free-flowing, white crystalline solid.
