CAS #504-63-2
Neopentyl glycol (NPG) is a white crystalline solid widely recognized as the standard diol for high-performance coating resins. It is used to synthesize polyesters with saturated or unsaturated di-acids, making it suitable for applications such as paints, lubricants, plasticizers, and fiberglass-reinforced plastics. NPG enhances resin stability against heat, light, and water due to its resistance to oxidation, non-polar nature, and steric retardation of hydrolysis.
