Hydrogenated bisphenol A epoxy resin 518, also known as hydrogenated bisphenol A diglycidyl ether, colorless to light yellow transparent liquid.
CAS number: 30583-72-3
Structural formula:
The molecular structure is similar to that of bisphenol A epoxy resin, and the physical and mechanical properties of the cured material are similar to that of bisphenol A epoxy resin, but its molecules do not contain unsaturated bonds and have strong weather resistance. It is mainly used for outdoor electrical insulation materials, outdoor storage tanks, steel structure coatings and concrete DAMS and other pot-sealing materials. Since the viscosity is much lower than that of bisphenol A epoxy resin, more fillers can be added to reduce the cost and eliminate shrinkage.
