Coatings and coating systems containing high density metal material

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.
