DIACRON™ ER-502 is a polyester resin with excellent solvent solubility. It is a high acid value and high molecular weight (Mw)-grade and is optimal as a binder for paints and inks due to its excellent pigment dispersibility. It improves hardness, heat resistance, toughness, and solvent resistance by using curing agents such as isocyanates and epoxy resins.
*DIACRON™ is provided by Mitsubishi Chemical Corporation, a member of the Mitsubishi Chemical Group.
