ANTI-OZONANT COMPOSITION FOR A CROSSLINKED RUBBER ARTICLE
An anti-ozone protective composition for a crosslinked rubber article; is based on at least one chlorinated elastomer, at least one hydrocarbon solvent and at least one polar aprotic solvent. A rubber article comprises at least one elastomeric surface in contact with air, said surface being completely or partly coated with said composition.
Self-Disinfecting Frequently Touched Surface
A frequently-touched surface for use by multiple users includes a surface protected by a laminate structure. The laminate structure includes a self-sterilizing sulfonated polymeric outer layer, sulfonated to a certain % to kill at least 95% microbes within 30 minutes of contact. The self-sterilizing sulfonated polymer layer can be applied to the frequently touched surface by any of coating, lamination, and spraying. The sulfonated polymer in embodiment is selected from perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer has a degree of sulfonation of at least 10%.

Chlorosulfonated polyethylene latex
A chlorosulfonated polyethylene latex, which is safe for living bodies and the environment and can be used as a latex component in a resorcin-formalin-latex adhesive, contains an aqueous dispersion medium, chlorosulfonated polyethylene, and an emulsifying agent of a polyoxyalkylene alkyl ether sulfate of formula (I) below and a fatty acid salt. The latex is excellent in standing stability and mechanical stability. In formula (I), R.sup.1, R.sup.2, n, and M represent an alkyl group of 6 to 20 carbon atoms, hydrogen or a methyl group, an integer of 2 to 40, and an alkali metal, respectively.

Composite article having protective coating
A composite article includes a substrate and a protective coating on at least a portion of the substrate. The protective coating includes reinforcement particles dispersed within an elastomeric matrix that is modified with a silicon-containing modifier selected from polysilsesquioxane, polyhedral oligomeric silicate, polyhedral oligomeric silsesquioxane (POSS), and combinations thereof. The reinforcement particles are selected from carbon, nickel metal, and combinations thereof. The protective coating is multi-layered and includes a distinct first layer and a distinct second layer that is contiguous with the distinct first layer such that each of the distinct first layer and the distinct second layer have an exposed outer surface.
