Abstract

A coating applied to an article is provided. The coating has an adhesive material, in contact with at least one substrate of the article. The coating has a plurality of high density metal pellets disposed in the adhesive material. The high density metal pellets are in an amount of at least 90% by weight of the total weight percent of the coating, and each high density metal pellet has a diameter of at least 0.04 inch. The coating further has a polymer material. The coating is applied to the at least one substrate of the article to obtain a mass-enhanced, coated article. The coating has a coating thickness of at least 0.25 inch. The coating thickness and the amount of high density metal pellets are sufficient to provide an attenuation of vibration of the coated article and a reduced risk of unwanted ergonomic effects.

First claim

What is claimed is:

1. A coating applied to an article, the coating comprising:
an adhesive material, in contact with at least one substrate of the article;
a plurality of high density metal pellets disposed in the adhesive material, to form a metal adhesive matrix, the plurality of high density metal pellets being in an amount of at least 90% (ninety percent) by weight of the total weight percent of the coating, and each high density metal pellet having a diameter of at least 0.04 inch; and
a polymer material applied over the metal adhesive matrix,
wherein obtaining a mass-enhanced, coated article, the coating having a coating thickness of at least 0.25 inch, and the coating thickness and the amount of high density metal pellets being sufficient to provide an attenuation of vibration of the coated article and a reduced risk of unwanted ergonomic effects.

2. The coating of claim 1 , wherein the article comprises one of, an implement, a tool, a percussive tool including a rivet gun, a bucking bar, a handle, or a glove.

3. The coating of claim 1 , wherein the adhesive material is a binder material and comprises one or more of, a viscoelastic adhesive, a mastic viscoelastic adhesive, a hot-melt adhesive, a spray adhesive, a liquid adhesive, an adhesive glue, or a pressure sensitive adhesive.

4. The coating of claim 1 , wherein each high density metal pellet comprises a high density metal material comprising one or more of, tungsten carbide, tungsten, iron, copper, nickel, lead, molybdenum, steel, inconel, platinum, tin, silver, zinc, bronze, or alloys of one or more of the high density metal materials thereof.

5. The coating of claim 1 , wherein the diameter of each high density metal pellet is in a range of 0.04 inch to 0.10 inch, and further wherein each tungsten carbide pellet has a shape comprising one of, a spherical shape, a rod shape, an elliptical shape, or a disk shape.

6. The coating of claim 1 , wherein the polymer material comprises a polymer comprising one of, polyolefin, polyethylene (PE), polypropylene (PP), nylon, polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), perfluoroalkoxy alkanes (PFA), ethylene tetrafluoroethylene (ETFE), polyester, polyether ether ketone (PEEK), polyvinyl chloride (PVC), polyimide (PI), polyamide, polyurethane (PU), polystyrene (PS), polyvinylidene fluoride (PVDF), or polyvinyl acetate (PVAC).

7. The coating of claim 1 , wherein the polymer material comprises a cross-linked polyolefin heat shrink sleeve.

8. The coating of claim 1 , wherein the coating thickness is in a range of 0.25 inch to 0.5 inch.

9. The coating of claim 1 , wherein:
the amount of high density metal pellets comprises 90% to 98% by weight of the total weight percent of the coating;
the adhesive material is in an amount comprising 1% to 9% by weight of the total weight percent of the coating; and
the polymer material is in an amount comprising 1% to 5% by weight of the total weight percent of the coating.

10. A coating applied to a percussive tool, the coating comprising:
an adhesive material, in contact with at least one substrate of the percussive tool;
a plurality of tungsten carbide pellets disposed in the adhesive material, to form a metal adhesive matrix, the plurality of tungsten carbide pellets being in an amount of at least 90% (ninety percent) by weight of the total weight percent of the coating, and each tungsten carbide pellet having a diameter of at least 0.04 inch; and
a polymer material applied over the metal adhesive matrix,
wherein obtaining a mass-enhanced, coated percussive tool, the coating having a coating thickness of at least 0.25 inch, and the coating thickness and the amount of tungsten carbide pellets being sufficient to provide an attenuation of vibration of the coated percussive tool and a reduced risk of unwanted ergonomic effects.

11. The coating of claim 10 , wherein the percussive tool comprises a rivet gun, and the coating is applied to a barrel substrate of the rivet gun.

12. The coating of claim 11 , wherein the coating is further applied to a handle substrate of the rivet gun.

13. The coating of claim 10 , wherein the adhesive material is a binder material and comprises one or more of, a viscoelastic adhesive, a mastic viscoelastic adhesive, a hot-melt adhesive, a spray adhesive, a liquid adhesive, an adhesive glue, or a pressure sensitive adhesive.

14. The coating of claim 10 , wherein the polymer material comprises a cross-linked polyolefin heat shrink sleeve.

15. A coating system comprising:
an article having at least one substrate configured to be coated; and
a coating comprising:
an adhesive material;
a plurality of high density metal pellets disposed in the adhesive material, to form a metal adhesive matrix, the plurality of high density metal pellets being in an amount of at least 90% (ninety percent) by weight of the total weight percent of the coating, each high density metal pellet having a diameter of at least 0.04 inch; and
a polymer material applied over the metal adhesive matrix,

wherein obtaining a mass-enhanced, coated article, the adhesive material of the coating being in contact with the at least one substrate, and the coating having a coating thickness of at least 0.25 inch, and the coating thickness and the amount of high density metal pellets being sufficient to provide an attenuation of vibration of the coated article and a reduced risk of unwanted ergonomic effects.

16. The coating system of claim 15 , wherein the article comprises one of, an implement, a tool, a percussive tool including a rivet gun, a bucking bar, a handle, or a glove.

17. The coating system of claim 15 , wherein the adhesive material is a binder material and comprises one or more of, a viscoelastic adhesive, a mastic viscoelastic adhesive, a hot-melt adhesive, a spray adhesive, a liquid adhesive, an adhesive glue, or a pressure sensitive adhesive.
