What is Neopentyl glycol diglycidyl ether?
Neopentyl glycol diglycidyl ether is a low viscosity, aliphatic diepoxy functional compound that serves as an excellent reactive diluent for epoxy resin systems. Its unique neopentyl structure provides outstanding resistance to thermal degradation, weathering, and chemical attack. NPGDGE effectively reduces the viscosity of epoxy formulations while maintaining good mechanical properties and chemical resistance in the cured system. This product offers excellent compatibility with various epoxy resins and demonstrates low volatility and minimal skin irritation compared to conventional epoxy diluents.
