coatingsthat

Coatingsthat is used here as a conceptual label for coatings that are applied to surfaces to protect, decorate, or impart functional properties. They form a continuous film that adheres to the substrate and can be a few micrometers to several tens of micrometers thick. The main goals include restricting water and oxygen ingress, reducing wear, and improving appearance.

Common coating classes include organic polymer coatings (epoxy, polyurethane, acrylics, alkyds), inorganic coatings (chromate, silicate-based), metallic coatings (zinc, nickel, chromium plating), and ceramic coatings (alumina, zirconia). Hybrid and composite coatings combine properties of different materials.

Functional coatings provide specialized properties such as anti-corrosion, anti-microbial, hydrophobic or superhydrophobic, anti-icing, conductive or dielectric, and optical coatings for reflectivity or color control.

Application methods include spraying, dipping, brushing, electrocoating, and advanced deposition techniques like thermal spray or vapor deposition. Selection depends on substrate, performance requirements, environmental impact, and cost. Performance is evaluated by adhesion, hardness, abrasion resistance, chemical resistance, and environmental durability, with standards such as ISO 12944 and ASTM D3359.
