Abstract: Provided are methods and systems for dispensing filament adhesive onto a target substrate. A filament adhesive is applied on a target substrate according to a bead application plan, then the applied bead is checked against performance criteria. A second bead application plan is generated, and subsequent filament bead applied according to the second bead application plan.

Abstract: Described are adhesive compositions containing a block copolymer component that includes a midblock segment and a plurality of end block segments, each end block segment comprising polystyrene, a (meth)acrylic functional additive having a glass transition temperature of from 50° C. to 160° C., a first tackifier compatible with the midblock segment and containing a hydrocarbon, and a second tackifier compatible with the end block segments and containing a polyphenylene ether. These compositions are useful in providing pressure-sensitive adhesives that are melt processible, display a high temperature resistance, and effectively bond to low surface energy substrates.
