1. A single-component adhesive composition comprising:

a curable mixture comprising an ethylenically unsaturated monomer;

a microencapsulated hydrophobic amine having a molecular weight of at least 175 Da dispersed within the curable mixture; and

an oxidant that can generate a free radical upon reaction with the hydrophobic amine, such as a peroxide;

wherein the composition is packaged in a sealed container such that the composition protected from atmospheric moisture,

wherein when packaged in the sealed container, the adhesive composition remains uncured for a period of at least 90 days.
