    Bisphenol F epoxy resin, also known as bisphenol F diglycidyl ether, or BPF for short, is a new type of epoxy resin developed by reducing the viscosity of bisphenol A epoxy resin and having the same properties. Bisphenol F epoxy resin can be used in solvent-free solid coatings, casting and casting molding materials, laminated materials and other fields requiring low liquid viscosity (such as glass fiber reinforced plastics and carbon fiber composites). Because bisphenol F epoxy resin or bisphenol F-type and bisphenol a type epoxy resin has good heat resistance, water resistance and electrical properties, it can also be used in casting and potting materials for transformers, sealing materials for semiconductors, conductive adhesives for semiconductors, etc.
