Abstract: A method of preparing specimens for peel-adhesion testing. The method includes applying a first predetermined amount of light-curable material to a substrate coupon, placing a first surface of a substantially transparent peel media in contact with the light-curable material disposed on the substrate coupon, where the substantially transparent peel media includes a second surface spaced from the first surface, and exposing the first predetermined amount of light-curable material disposed between the substrate coupon and the first surface to a light source to cure the first predetermined amount of light-curable material, with light from the light source passing through the substantially transparent peel media to the substrate coupon.

Abstract: The present application is directed to polysulfide sealant formulations, application of such sealants, and methods for reducing the density of polysulfide sealant formulations.

Abstract: A rubber substrate has a material diffusion barrier, and a method produces the same. In an embodiment, a method for producing a material diffusion barrier on a rubber substrate include exposing the rubber substrate to a cationic solution to produce a cationic layer on the rubber substrate. The method also includes exposing the cationic layer to an anionic solution 5 to produce an anionic layer on the cationic layer. The anionic layer comprises graphene oxide. The layer includes the cationic layer and the anionic layer. The layer comprises the material diffusion barrier.

Abstract: Improved polysulfide sealant formulations, application of such sealants, and methods for reducing the density of polysulfide sealant formulations are disclosed.
