The molecular structure of epoxy bisphenol fluorene is as follows:

Physical constants：

technical indicators：

Epoxy based bisphenol fluorene, as an important thermosetting epoxy resin containing multiple benzene ring fluorene structures, is characterized by its excellent mechanical properties, good heat resistance, chemical resistance, wear resistance, and strong adhesive strength. The introduction of fluorene structure can reduce the crosslinking density of resin after curing, while an increase in the number of benzene rings can improve the rigidity of molecular chains, increase the glass transition temperature of the resin, and also increase the non polarity of molecules, reducing the water absorption of the resin. Therefore, the moisture and heat resistance of this resin is greatly improved. Widely used in composite material matrices, insulation materials, adhesives, and optical coating materials.
