Application
2,2-Dimethyl-1,3-propanediol (Neopentyl glycol, NPG, CAS 126-30-7) is a high-purity diol with exceptional thermal and hydrolytic stability due to its neopentyl structure. It is a key building block for saturated polyester resins, alkyd resins, polyurethane coatings, synthetic lubricants, and plasticizers. NPG imparts superior weather resistance, chemical resistance, and gloss retention to powder coatings, coil coatings, and automotive topcoats. It is also used in the production of fiberglass-reinforced plastics, adhesives, and printing inks. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high-purity NPG with flexible scaling from R&D to commercial tons.
