Abstract
The present invention is directed to an adhesive composition comprising a crosslinkable acrylic copolymer, a multi-functionalized crosslinkable oligomer and a photoinitiator wherein the composition exhibits excellent wet out characteristics as reflected in a tan delta value of at least 0.5, preferably greater than 0.5, more preferable greater than 0.8 as measured at 20° C. resulting from a first curing stage, and improved stiffness and temperature resistance as reflected in a storage elastic modulus of at least 300,000 Pa at 20° C. and a shear adhesion failure temperature of at least 425° F. (218.3° C.) at 1 Kg/in(0.155 Kg/cm), respectively, which result from a second sequential curing stage.
