Applications of barrier coating mixtures containing in a carrier liquid, (a) an elastomeric (preferably butyl-containing) polymer; (b) a dispersed exfoliated layered filler having an aspect ratio greater than 25; and (c) at least one surfactant, wherein the solids content of the mixture is less than 30% and the ratio of polymer (a) to filler (b) is between 20:1 and 1:1 include coated articles, which are elastomeric, e.g., sports balls and inflatable articles. Methods of manufacturing such coated products are also encompassed.

Barrier coating mixtures contain in a carrier liquid, (a) an elastomeric (preferably butyl-containing) polymer; (b) a dispersed exfoliated layered filler having an aspect ratio greater than 25; and (c) at least one surfactant, wherein the solids content of the mixture is less than 30% and the ratio of polymer (a) to filler (b) is between 20:1 and 1:1. Coated articles, which are rigid or flexible and elastomeric, and free-standing films and membranes, which are flexible and elastomeric, are produced using the barrier coating mixtures.
