NPG is used as a building block for the production of polyurethane adhesive resins (polyester polyol and polycarbonate diol) providing flexibility and adhesion.
NPG is mainly used as a building block for coating resins such as saturated polyesters (major application in powder coatings), alkyds (e.g. Coating metal furniture and fixtures), unsaturated polyesters (e.g. artificial marble and gelcoat for boats), and finally for the production of polyurethane resins (polyester polyol and polycarbonate diol).
NPG provides high hydrolytic stability, high UV stability (UVA/UVB), weatherability, adhesion and a good balance between hardness and flexibility.
NPG is utilized in the production of polyester lubricants and plasticizers.
