Curable compositions

A curable composition comprising:

• an isocyanate-functional prepolymer comprising a reaction product of reactants comprising a polyol and an isocyanate having an isocyanate equivalent weight of 200 g/eq to 2,000 g/eq and present in an amount of 20 percent by weight to 86 percent by weight;
• an epoxy-containing component comprising Bisphenol A, Bisphenol F, and/or an epoxy novolac, the epoxy-containing component present in an amount of 10 percent by weight to 75 percent by weight;
• a latent curing agent comprising an amine hydrogen in an amount of at least 0.5:1 to 3:1 based on a ratio of molar equivalents of amine hydrogens to total molar equivalents of isocyanate functional groups plus epoxide functional groups and having an ability to react with at least one of the isocyanate-functional prepolymer and the epoxy-containing component upon exposure to an external energy source;
• an elastomeric dispersion comprising elastomeric particles in an amount of 10% by weight to 35% by weight based on total weight of the elastomeric dispersion, wherein the elastomeric particles have a core-shell structure;
• and
• optionally an epoxy carrier resin incorporated into the elastomeric particles;
• wherein the amount by weight is based on total weight of the composition.
