Abstract:
1. A process for bonding a first substrate to a second substrate with a low application temperature hot melt adhesive comprising the steps of: (1) applying to at least a portion of the first substrate a low application temperature hot melt adhesive; (2) bringing the second substrate in contact with the adhesive present on the first substrate, and (3) allowing the adhesive to solidify, whereby the first substrate is bonded to the second substrate; wherein the adhesive comprises: wherein the sum of the total wt % of the adhesive equals to 100; and wherein the adhesive has a viscosity of below about 11,000 centipoises at 120° C., a yield stress (12 in/min extensional rate) range of from about 7 to about 50 psi at 25° C., a cube flow of less than about 200% at 60° C., and a cross-over temperature (when G″=G′) greater than about 70° C.
