In the field of composite materials, an increasing number of companies are using FR-4 epoxy insulation boards to replace old materials. Among the widely used copper-clad boards in the electronics industry, FR-4 material has maintained its dominant position.

Epoxy resin refers to a general term for polymer compounds with a polymer chain structure containing two or more epoxy groups, which belong to thermosetting resins. The representative resin is bisphenol A type epoxy resin.

Epoxy resin is generally used in conjunction with additives to obtain application value. Additives can be selected according to different purposes, and commonly used additives include curing agents, modifiers, fillers, diluents, and others.

Viscosity reduction: The viscosity of epoxy resin varies greatly according to different applications, such as painting, lining, casting, and impregnation. To reduce the viscosity, diluents can be added, which can be classified into non-reactive diluents and reactive diluents according to their functions.
