Epoxies are one of the most versatile classes of polymers with diverse applications such as coatings, adhesives, electronic encapsulants and composites.However, the application of epoxy cured in the higher-requested fields is limited as its brittleness.Aliphatic epoxy, a low viscosity resin, has the advantage of less shrinkage and brittleness than other resins after curing and its resin could be cured significantly by longtime irradiation of UV light.
