💡 Applications of Neopentyl Glycol

1. Polyester Resins & Powder Coatings

NPG is a primary raw material in saturated polyester resins, widely used in automotive and industrial powder coatings. Its structure improves weather resistance, color retention, and film durability.

2. Alkyd Resins for Paints

It enhances the gloss, hardness, and chemical resistance of alkyd paints and enamels. NPG’s resistance to hydrolysis is especially valuable in outdoor applications.

3. Plasticizers and Lubricants

Used in the production of esters, Neopentyl Glycol acts as a base for synthetic lubricants and plasticizers, particularly for high-performance applications requiring thermal and oxidative stability.

4. Adhesives and Sealants

NPG improves the adhesion strength, flexibility, and chemical resistance in adhesives, helping to extend the service life of bonded materials.
