Abstract: Barrier coating mixtures contain in a carrier liquid, (a) a non-elastomeric polymer; (b) an exfoliated layered platelet-like silicate filler which may or may not have been acid or base treated that has not been functionalized with organic cations having an aspect ratio greater than 25; and (c) at least one additive, wherein the total solids content is less than 30% and the amount of filler is between 5% to about 60% of the total solids content. Coated articles and containers, freestanding films and packaging films are produced using the barrier coating mixtures. Methods of manufacturing such coated products are also encompassed.

Abstract: Barrier coating mixtures include (a) a mixture of pre-vulcanized and non-vulcanized elastomeric polymers; (b) an acid or base treated dispersed, substantially exfoliated silicate filler material that has not been functionalized with organic cations having an aspect ratio greater than 25; and (c) at least one additive, wherein the total solids content is less than 30% and the amount of filler is between 5% to about 60% of the total solids content. The coating retains its permeability properties under strain and has a strain to first damage of at least 10% biaxial elongation at 0% RH. Coated articles, free standing films and membranes, which are flexible and elastomeric, are produced using the barrier coating mixtures. Methods of manufacturing of such coated products are also encompassed.
