First Claim
Patent Images
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 190°

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 190°

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 190°
