Usage
epoxy resin(1) Compared with epoxy resins made from bisphenol A, epoxy resins made from bisphenol F have characteristics such as low viscosity and excellent workability. They can be applied to solvent - free to ultra - high - solid - content coatings, and can also be applied in fields such as lining materials, flooring materials, casting materials, impregnating materials, and laminated materials.
polycarbonate resin(2) Polycarbonate resins made from bisphenol F and phosgene are easily soluble in low - boiling - point organic solvents such as dichloromethane, have a low softening point, and have good processing and molding properties. They are elastic even when subjected to very large damage, and are suitable for manufacturing molding materials or films.
polyester resin(3) The biphenyl - type diol obtained by the addition of bisphenol F and alkylene oxide, and the resin obtained by reacting with dibasic acids, etc., has a low viscosity and excellent mechanical and chemical properties, and is particularly suitable for manufacturing corrosion - resistant materials.
others(4) In addition, bisphenol F can also be used to produce oil - soluble phenolic resins, flame retardants, antioxidants, and surfactants, etc.
