Article Synopsis
- Organically coated steels are important for outdoor applications due to their need for strong corrosion resistance, typically enhanced by fossil fuel-derived clearcoats.
- A study explored using tetraethoxysilane (TEOS)-based sol-gel coatings on polyurethane-coated steels, varying TEOS concentration to assess effectiveness.
- The 10% TEOS concentration produced dense, uniform coatings with significantly better corrosion resistance, while the 2.5% concentration resulted in poor coating quality, indicating the need for optimal TEOS levels in future sol-gel research.
Viruses such as SARS-CoV-2 can remain viable on solid surfaces for up to one week, hence fomites are a potential route of exposure to infectious virus. Copper has well documented antiviral properties that could limit this problem, however practical deployment of copper surfaces has been limited due to the associated costs and the incompatibility of copper metal in specific environments and conditions. We therefore developed an organic coating containing an intelligent-release Cu pigment based on a cation exchange resin.
