What is claimed is: 1. A method of sealing, baffling or reinforcing a portion of an automotive vehicle, the method comprising: providing an activatable material, the activatable material including: i) 30% to about 80% by weight epoxy resin; ii) 5% to about 25% by weight thermoplastic polyether sele
What is claimed is: 1. A method of sealing, baffling or reinforcing a portion of an automotive vehicle, the method comprising: providing an activatable material, the activatable material including: i) 30% to about 80% by weight epoxy resin; ii) 5% to about 25% by weight thermoplastic polyether selected from a polyetheramine and a polyamino ether; and iii) a curing agent; applying the activatable material to a surface of a carrier member; inserting the carrier member with the activatable material disposed thereon into a cavity that is at least partially defined by a structural member of the automotive vehicle; and exposing the activatable material to heat thereby activating the activatable material to bond to surfaces of the structural member; wherein the thermoplastic polyether has a melt index between about 25 and about 75 per 10 minutes under a load of 2.16 Kg at a temperature of 190째 C. 2. A method as in claim 1 wherein the step of exposing the activatable material occurs in an automotive e-coat or painting operation and the activating of the activatable material includes foaming and curing of the activatable material. 3. A method as in claim 1 wherein the thermoplastic polyether includes a polymer backbone and includes aromatic ether/amine repeating units in the backbone. 4. A method as in claim 1 further comprising, forming the thermoplastic polyether by reacting a difunctional amine with a glycidyl ether. 5. A method as in claim 1 wherein the activatable material includes a blowing agent. 6. A method as in claim 5 wherein the blowing agent is selected from an azodicarbonamide, a dinitrosopentamethylenetetramine, a 4,4i-oxy-bis-(benzenesulphonylhydrazide), a trihydrazinotriazine and a N,Ni-dimethyl-N,Ni-dinitrosoterephthalamide. 7. A method as in claim 5 wherein the activatable material includes an ingredient selected from a filler, a clay, a blowing agent accelerator, a curing agent accelerator, and a flexiblizer. 8. A method as in claim 1 wherein the activatable material further includes a polymeric material selected from an elastomer-containing adduct, a halogenated polymer, a polycarbonate, a polyketone, a urethane, a polyester, a silane, a sulfone, an allyl, an olefin, a styrene, an acrylate, a silicone, a phenolic, a polyphenylene oxide, a terphthalate and an acetate. 9. A method as in claim 1 wherein applying the activatable material includes extruding the activatable material onto the surface of the carrier member. 10. A method as in claim 1 wherein the activatable material is substantially tack free. 11. A method as in claim 1 wherein the step of applying the activatable material to a surface of a carrier member forms a reinforcement member wherein the carrier member is skeletal and includes a plurality of ribs. 12. A method of sealing, baffling or reinforcing a portion of an automotive vehicle, the method comprising: providing an activatable material, the activatable material including: i) between about 40% and about 60% by weight epoxy resin; ii) between about 5% and about 25% by weight thermoplastic polyether selected from a polyetheramine and a polyamino ether; and iii) a curing agent; locating the activatable material within a cavity or upon a surface of a structure of the automotive vehicle; and exposing the activatable material to heat thereby activating the activatable material to bond to surfaces of the structure; wherein the thermoplastic polyether has a melt index between about 25 and about 75 per 10 minutes under load of 2.16 Kg at a temperature of 190째 C. 13. A method as in claim 12 wherein the step of exposing the activatable material occurs in an automotive e-coat or painting operation and the activating of the activatable material includes foaming and curing of the activatable material. 14. A method as in claim 12 wherein the activatable material includes a blowing agent. 15. A method as in claim 12 wherein the thermoplastic polyether includes a polymer backbone and includes aromatic ether/amine repeating units in the backbone. 16. A method as in claim 12 further comprising, forming the thermoplastic polyether by reacting a difunctional amine with a glycidyl ether. 17. A method as in claim 12 wherein the thermoplastic polyether is a copolymer of monoethanolamine and diglycidyl ether. 18. A method as in claim 12 wherein the thermoplastic polyether is formed by reacting an amine with an average functionality of 2 or less with a glycidyl ether. 19. A method as in claim 12 wherein the activatable material is substantially tack free. 20. A method of sealing, baffling or reinforcing a portion of an automotive vehicle, the method comprising: providing an activatable material, the activatable material including: i) 30% to about 80% by weight epoxy resin; ii) 5% to about 25% by weight thermoplastic polyether selected from a polyetheramine and a polyamino ether; iii) a curing agent; and iv) a blowing agent; locating the activatable material within a cavity or upon a surface of a structure of the automotive vehicle; and exposing the activatable material to heat in an automotive e-coat or paint operation thereby activating the activatable material to foam, cure and bond to surfaces of the structure; wherein the thermoplastic polyether is formed by reacting an amine with an average functionality of 2 or less with a glycidyl ether; and wherein the thermoplastic polyether has a melt index between about 25 and about 75 per 10 minutes under load of 2.16 Kg at a temperature of about 190째 C. 21. A method as in claim 20 wherein the thermoplastic polyether is a copolymer of monoethanolamine and diglycidyl ether. 22. A method as in claim 21 wherein the blowing agent is selected from an azodicarbonamide, a dinitrosopentamethylenetetramine, a 4,4i-oxy-bis-(benzenesulphonylhydrazide), a trihydrazinotriazine and a N,Ni-dimethyl-N,Ni-dinitrosoterephthalamide. 23. A method as in claim 22 wherein the activatable material includes an ingredient selected from a filler, a clay, a blowing agent accelerator, a curing agent accelerator, and a flexiblizer. 24. A method as in claim 23 wherein the activatable material further includes a polymeric material selected from an elastomer-containing adduct, a halogenated polymer, a polycarbonate, a polyketone, a urethane, a polyester, a silane, a sulfone, an allyl, an olefin, a styrene, an acrylate, a silicone, a phenolic, a polyphenylene oxide, a terphthalate and an acetate. 25. A method as in claim 24 wherein locating of the activatable material within a cavity or upon a surface of a structure of the automotive vehicle includes applying the activatable material to a carrier and inserting the carrier and the activatable material into the cavity of the structure of the automotive vehicle. 26. A method as in claim 24 wherein locating the activatable material includes extruding the activatable material onto the surface of the carrier member. 27.
