Abstract
Preventing cracking is very important for casting insulation material, especially for large epoxy casting insulation products, and improving material toughness is the most feasible approach. Various methods to improve the toughness of the bisphenol-anhydride epoxy system were studied. By properly combining the methods explained, impact toughness can be increased by two times, without much deterioration of other properties
