Product Introduction

◆ Special Performance

DMPA is a multifunctional compound with both hydroxyl and carboxyl groups. It can improve the water solubility and dispersibility of the resin; the introduction of polar groups can improve the adhesion of coatings and the dyeing properties of synthetic fibers. It is widely used in the production of various water-soluble resins, and the resins produced have good heat resistance, water resistance and color stability.
