Abstract
The hot melt adhesives of the present invention comprise a blend of at least one polyethylene, a tackifying resin, and a Fischer-Tropsch hydrocarbon wax. This hot melt adhesive has a novel combination of properties which meet the requirements necessary for use in rapid bonding or closing applications.
Claims8
An adhesive composition capable of being used as a hot melt adhesive containing as adhesive components a blend essentially consisting of
- a. about 50 to 80 percent by weight of at least one polyethylene having a melt viscosity of 500 to 20,000 centipoise at 190.degree. C.,
- b. about 10 to 40 percent by weight of at least one hydrocarbon tackifier resin, and
- c. about 7 to 15 weight percent of a high melting synthetic Fischer-Tropsch hydrocarbon wax.
An adhesive composition capable of being used as a hot melt adhesive containing as adhesive components a blend essentially consisting of
- a. about 62 weight percent of at least one polyethylene having a melt viscosity of 500 to 20,000 centipoise at 190.degree. C.,
- b. about 27 weight percent of at least one hydrocarbon tackifier, and
- c. about 11 weight percent of a high melting synthetic Fischer-Tropsch hydrocarbon wax.
