A water based paint that can be used to form a superhydrophobic coating includes a fluorinated particulate filler, a water soluble or water suspendable resin, and an aqueous solvent. The superhydrophobic paint can be applied to a surface where the loss of the solvent results in a superhydrophobic coating.

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.
