This effort evaluates bioinspired coatings for use in a top-coat type application to identify those technologies that may improve decontamination capabilities for painted surfaces. This report details results for evaluation of four commercially available treatments NANOskin Hydro Express, Rust-Oleumregistered trademark NeverWetregistered trademark, Eagle One Superior NanoWaxregistered trademark, and Rust-Oleumregistered trademark Wipe New. Commercially available treatments offer some potential advantages over the less mature technologies otherwise evaluated by this effort. Hazards, deposition approaches, and production scaling have been addressed, and the materials are suitable for immediate use as appropriate. Given the potential for rapid adoption and reduced costs, evaluation of relevant commercial treatments was completed following standard approaches. Retention of the simulants paraoxon, methylsalicylate, dimethyl methylphosphate, and diisopropyl fluorophosphates following treatment of contaminated surfaces with a soapy water solution is reported. Wetting behaviors and target droplet diffusion on the surfaces are also discussed.
