Claims13
The method of sealing the ends of an insulated electrical conductor against penetration by moisture and other contaminants comprising the steps of passing solid thermoplastic adhesive from a remote reservoir to a means for melting said adhesive and applying molten thermoplastic adhesive to the open ends of an insulated electrical conductor in a manner whereby said adhesive bonds to the insulated surface of said insulated conductor and seals the open ends of said conductor against penetration by moisture and other contaminants, wherein said thermoplastic adhesive comprises an ethylene vinyl acetate polymer characterized by:
- a melt temperature range of from about 300.degree. F. to about 375.degree. F.;
- a viscosity of about 1800 cps at 375.degree. F.;
- and
- a specific gravity of about 0.95 to about 0.99 at 75.degree. F.
