Products Description
NPGDGE(CAS 17557-23-2)contains two epoxy groups and exhibits high reactivity.
During the curing process, it participates in crosslinking to form chain-like and network structures, imparting excellent mechanical properties-such as tensile, flexural, compressive, and impact resistance-to the cured resin. Furthermore, it demonstrates good compatibility with bisphenol A-type epoxy resins, making it well-suited for use as a reactive diluent.

FAQ
Q1:What are the advantages of NPGDGE compared to monofunctional epoxy diluents?
Re: Its dual epoxy groups can participate in cross-linking, preventing it from remaining in the system as a small-molecule residue; consequently, there is less degradation of mechanical properties after curing.
Q2:Storage Instructions
Re:Store in a cool, dry place, protected from light and moisture. Keep the container tightly sealed. It is recommended to store at temperatures below 25°C. Keep away from heat sources and oxidizing agents, and avoid prolonged exposure to direct sunlight.
Q3:Could NPGDGE be used with amine or anhydride curing agents?
Re: Yes, it is compatible with most epoxy curing systems, including amines, modified amines, and anhydrides.
Q4: Will it thicken or deteriorate if stored for a long time?
Re: It remains stable when stored in a sealed container at low temperatures; however, prolonged exposure to high temperatures can lead to gradual self-polymerization, causing an increase in viscosity.
