Abstract
A fastener assembly, such as a nail assembly, includes a row of fasteners held together and maintained in position by an extrudable thermoplastic adhesive composition containing a particulate filler, an extrudable thermoplastic resin reacted with a polar compound, and optional quantities of an additional thermoplastic resin. The adhesive composition provides the fastener assembly with increased rigidity, reduced bending and buckling, and reduced shearing requirements for separating an individual fastener from the row. The invention also includes an adhesive composition useful in the fastener assembly.
Claims26
A fastener assembly for use in a fastener driving tool, comprising:
- a row of fasteners arranged substantially parallel to each other;
- and
- an extrudable adhesive composition bonded to the fasteners and maintaining them in the substantially parallel arrangement in the row;
- the adhesive composition including at least an extrudable polymer backbone which has been reacted with a polar moiety, and about 3-75% of a particulate filler based on the weight of the adhesive composition.
A fastener assembly for use in a fastener driving tool, comprising:
- a row of fasteners arranged in a substantially flat, planar configuration;
- and
- an extrudable adhesive composition bonded to the fasteners and maintaining them in the row;
- the extrudable adhesive composition including an active ingredient functionalized with a polar moiety, and about 3-75% of a particulate filler based on the weight of the adhesive composition;
- the filler being substantially chemically inert to the polar moiety.
