Material Notes:
NPG is a diol with two hydroxyl groups located in the 1,3-position on the primary carbon atom. Additionally, it has two methyl groups instead of the usual two hydrogen atoms on the a-carbon atom. Its unique structure is responsible for allowing rapid esterification, high chemical and thermal stability of NPG as well as high crystalline and weatherability.Applications: Powder Coating Resins, Alkyd Coating Resins, Fiber Glass Reinforced Resins, Polyester Polyols PlasticizerCAS No. 126-30-7Information provided by LG Chemical
