Blending Resins For SIS-Based Nonwoven, Hot Melt Adhesives
This article investigates the effect on adhesive performance of blending a fully hydrogenated hydrocarbon resin with different grades and amounts of pure monomer aromatic hydrocarbon resins. It also reports the results of blending these resins to reproduce the effect of a chemical-resin modification (partial C9-resin hydrogenation) on SIS-based (styrene-isoprene-styrene) hot melt adhesive performance.
The results show that blends of aromatic and aliphatic hydrocarbon resins can be used to modify polymer and resin compatibility in SIS-based nonwoven, hot melt adhesives. In fact, they can effectively replace and can be a competitive alternative to partially hydrogenated C9 resins in these systems.
