1. Description
Chemical name: Neopentane Glycol Diglycidyl Ether，
Its molecular contains two epoxy groups which can take part in curing reaction of epoxy resin when curing, and form chain and net conformation, although the diluent effect of 678 is as good as that of single glycidyl ether, the performance of its cured epoxy such as compressive strength, flexural strength, tensile strength, impact strength and adaptive time is better than that of single glycidyl ether.
Molecular formula：C11H20O4， molecular weight：216，
CAS Number: 17557-23-2
Structural Formula:
Appearance: Colorless transparent liquid
