ABSTRACT:
The present invention relates to a sprayable hotmelt adhesive composition, a process for preparing the same, and a method of using the same. The hot melt adhesive composition contains 30 weight percent to 70 percent of one or more poly-α-olefins; 5 weight percent to 30 weight percent of at least one oil; and 20 weight percent to 60 weight percent of at least one hydrocarbon resin having a softening range of 70° C. to 140° C. The poly-α-olefin or the mixture of poly-α-olefins has a softening point of 70° C. to 30° C. and a melt viscosity at 190° C. of 1,000 mPas to 20,000 mPas. The hotmelt adhesive has a viscosity at 150° C. of 500 mPas to 4,000 mPas.
