wherein the device is heated to a temperature of at least about 30° C. but below an activation temperature of the activatable material and contacted with the particulate of the activatable material, so that the particulate activatable material softens and adheres to the device.

2 . The activatable material coated device of claim 1 , wherein the activatable material further comprises a dispersant;

wherein the molecular weight of the dispersant is less than about 50,000 amu; and

wherein the dispersant is selected from a paraffin wax or an ethylene propylene diene monomer.

3 . The activatable material coated device of claim 1 , wherein upon exposure to an elevated temperature, the activatable material expands to at least 100%, at least 500%, at least 1000% or even at least 3000% of its original size.

4 . The activatable material coated device of claim 3 , wherein the one or more fillers or reinforcing components includes one or more of calcium carbonate, aramid pulp, or any combination thereof.

5 . The activatable material coated device of claim 3 , wherein the activatable material is in a pellet form prior to being milled.

6 . The activatable material coated device of claim 1 , wherein the activatable material includes about 10% to about 70% by weight of a polymeric admixture;

wherein the polymeric admixture includes one or more acrylates and one or more acetates;

wherein the polymeric admixture is at least about 40% of the activatable material and the one or more acrylates comprise about 40% to about 85% of the polymeric admixture and the one or more acetates comprise about 7% to about 35% of the polymeric admixture.

7 . The activatable material coated device of claim 6 , wherein the polymeric admixture includes about 6.0% to about 20% of a tackifier, the tackifier being a hydrocarbon resin, and about 0.1% to about 10% by weight of an epoxy resin.

8 . The activatable material coated device of claim 7 , wherein the activatable material includes 8% or greater of the blowing agent and the blowing agent accelerator, the blowing agent being selected from an amine or an amide and the blowing agent accelerator being selected from a metal salt or an oxide.

9 . The activatable material coated device of claim 1 , wherein upon exposure to an elevated temperature greater than about 180° C., the activatable material expands to a volume that is at least 2000% greater than the volume of the activatable material in an unexpanded state.

10 . The activatable material coated device of claim 9 , wherein the activatable material is first pelletized and frozen thereafter.

11 . The activatable material coated device of claim 1 , wherein the curing agent has an activation temperature between about 60° C. and about 110° C.

12 . The activatable material coated device of claim 1 , wherein the activatable material is in a pellet form prior to being milled.
