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 ~C, of less than about 5 x 106 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.
L'invention a trait à une composition d'adhésif thermofusible sous forme de granules. La composition d'adhésif thermofusible est autocollante, présente un module de stockage G' à 25 ·C inférieur à environ 5 x 10?6¿ dynes/cm?2¿. Les granules sont enrobés en surface au moyen d'un agent facilitant la granulation, selon une concentration située de préférence entre environ 1 % en poids et environ 30 % en poids. L'agent facilitant la granulation est un constituant d'adhésif thermofusible ou une matière qui n'agit pas de manière sensiblement défavorable sur les propriétés adhésives. Les granules s'écoulent librement et présentent une surface sensiblement non collante.
