A hydrogenated bisphenol A epoxy resin is obtained from bisphenol A epoxy resin through a hydrogenation reaction. This modification enhances resistance to ultraviolet light and also improves color stability which is useful for outdoor applications. Specifically, the chemical resistance of the hydrogenated structure of the resin is advantageous because he increases the adaptability of the resin to many chemicals and solvents. In addition, its mechanical properties such as strength and hardness are remarkable along with superb insulation of electricity. These characteristics makes hydrogenated bisphenol A epoxy resin useful in high performance coatings, clear coatings and optics where aesthetics and durability are critical.
