Patent ID: 6890982

Claim:
A hot-melt adhesive composition, the adhesive composition comprising: (a) from about 25% to about 35% by weight of a thermoplastic copolymer consisting essentially of an ethylene containing copolymer, the copolymer being selected from the group consisting of an ethylene copolymer, an ethylene vinyl acetate copolymer, and copolymers and terpolymers thereof, the copolymer having a vinyl acetate content from about 18% to about 28%, the copolymer having a melt viscosity of from about 100,000-about 600,000 cP at 302 degrees F.; (b) from about 15% to about 40% by weight of a tackifier resin, the tackifier resin being characterized by having an acid number of from about 3 to about 10; (c ) from about 15 -about 35% by weight of a wax derived from a hydrogenated vegetable oil (a vegetable derived wax), the wax being characterized by having a melt viscosity of from about 50 to about 70 SUS at 210 degrees F., and a Mettler drop point of from about 130 degrees to about 170 degrees F.; and (d) the adhesive composition being characterized by having a DSC melt point of from about 50 degrees C. to about 80 degrees C., and a melt viscosity of from about 1000-about 5000 cps at 350 degrees F., the adhesive composition being capable of binding a fibrous cellulosic article to an article selected from the group consisting of a fibrous cellulosic article, wood, metal, glass and plastic.
