摘要： A curable composition includes (A) a first component having from 5.0 wt % to 39.0 wt %, based on the total weight of the first component, of a toughening agent component including a Bisphenol F based epoxy resin and an urethane acrylate component, a hardener component having at least one amine based hardener and is present in a ratio of 0.8 to 1.2, based on a number of equivalents of amino hydrogen groups in the hardener component to a number of equivalents of reactive groups in the first component capable of forming a covalent link with the amine reactive groups in the hardener, and an epoxy base component that accounts for a remainder of the total weight of the first component and that has at least one epoxy resin separately provided from the Bisphenol F based epoxy resin. The Bisphenol F based epoxy resin is present in an amount from 2.5 wt % to 50.0 wt % and the urethane acrylate component is present in an amount from 50.0 wt % to 97.5 wt %, based on the total weight of the toughening agent component. The urethane acrylate component includes the capping reaction product of an acrylate and an isocyanate terminated prepolymer and the isocyanate-terminated prepolymer is the reaction product of a polyisocyanate and at least a DMC derived polyol having a molecular weight of at least 3000 g/mol. The curable composition may further include (B) an optional second component that has at least one of a filler and any additional ingredient for a targeted application of the curable composition.
