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.   Features: Low temperature fusion Excellent metal adhesion Excellent pigment dispersion Can be used with cross-linking agents   Benefits: Solvent solubility High solid differentiation Use of biomass raw materials   Applications: PCM coatings For various types of inks Solventless & High Solids Coating   *DIACRON™ is provided by Mitsubishi Chemical Corporation, a member of the Mitsubishi Chemical Group.
