Described herein is a reworkable optically clear adhesive composition comprising: a hot melt adhesive present in an amount of at least about 40 wt. %; a pressure sensitive adhesive present in an amount of at 5 least about 10 wt. %; and titanium dioxide nanoparticles present in an amount of up to about 5 wt. %; wherein the weight percentage of each component is based on the total weight of solids of the adhesive composition. Also described herein is a display for an electronic device comprising the reworkable optically clear adhesive composition and a method of producing the display for an 10 electronic device.

Systems and methods for mating component parts are described. In some embodiments, a system for mating components may include a first component, a second component, a first adhesive, and a second adhesive. The first adhesive may be configured to set in less than 5 minutes after the first component and the second component are placed in a mating position, and the second adhesive may require greater than 5 minutes to set. The first adhesive, after setting, may have sufficient strength to maintain the first component and the second component in the mating position while the second adhesive sets.
