A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

Barriers for improved vapor mitigation are contemplated, such barriers being formed as a cured latex-asphalt mixture applied to the metal surface of a metallized substrate. The latex-asphalt mixture, prior to curing, comprises an emulsion of an asphalt component, a latex component, and water. Such barriers may be seen to substantially mitigate diffusion of chemical contaminants across the barriers in the form of gas or liquids. Also contemplated are methods for forming such barriers, whether fabricated off-site for installation on site, fabricated in-situ.
