Hot melt adhesive pellet comprising continuous coating of pelletizing aid

This invention relates to a hot melt adhesive composition in pellet form. The hot melt adhesive composition is pressure sensitive, having a storage modulus, G', at 25 DEG C., of less than about 5x106 dynes/cm2. The pellets are coated with a pelletizing aid on the surface at a concentration pref...

Beschreibung
Zusammenfassung:	This invention relates to a hot melt adhesive composition in pellet form. The hot melt adhesive composition is pressure sensitive, having a storage modulus, G', at 25 DEG C., of less than about 5x106 dynes/cm2. The pellets are coated with a pelletizing aid on the surface at a concentration preferably ranging from about 1 wt-% to about 30 wt-%. The pelletizing aid is a hot melt adhesive component or a material which does not substantially adversely affect the adhesive properties. The pellets are free-flowing and have a substantially tack-free surface.
