Abstract
A single component liquid heat-curable adhesive formulation that is stable at room temperature. The formulation includes from about 5 to about 70 wt % of at least one acrylate monomer, from about 5 to about 94 wt % of an acrylate oligomer, and from about 0.1 to about 10 wt % of a thermal initiator selected from the group consisting of diacyl peroxides, benzoyl peroxides and peroxy esters. A photo initiator may be included thereby rendering the stable liquid formulation to be both heat-curable and UV-curable.
