The present disclosure is directed to processes, compositions and agents for inhibiting corrosion in various substrates, for example metal substrates. The present disclosure is also directed to corrosion inhibitors comprising organometallic polymers such as metal-organic frameworks (MOFs), including compositions and processes comprising MOFs for inhibiting corrosion in metal substrates.

Provided is a rust-preventive composition showing excellent rust-preventive performance for plate joining parts such as doors of automotive bodies, the composition having sufficient corrosion resistance and being capable of preventing dripping from automotive bodies. A rust-preventive composition including: a rust-preventive additive; a wax having a melting point within the range of 60° C. to 130° C. selected from microcrystalline waxes and polyethylene-based or polypropylene-based synthetic waxes; bentonite; a hydrogenated oil; and two or more kinds of diluents having different viscosities; the rust-preventive additive being contained in an amount within the range of 12% by mass to 39% by mass with respect to the total composition, the bentonite being contained in an amount within the range of 2% by mass to 6% by mass with respect to the total composition, the wax being contained in an amount within the range of 3% by mass to 13% by mass with respect to the total composition.

Coating compositions that include one or more epoxy resin compositions, one or more metal-containing compound and one or more curing agents are described. The compositions can be applied to steel substrates, including steel substrates such as steel pipe to resist attack by sour gas. When applied to a substrate and cured, these coating compositions demonstrate reduced permeability to hydrogen sulfide.

Disclosed are compositions, methods and processes for fabricating and using a device or other implement including a surface or surfaces having a nanoscale or microscale layer or coating of Si—O—N—P. These coatings and/or layers may be continuous, on the surface or discontinuous (e.g., patterned, grooved), and may be provided on silica surfaces, metal (e.g., titanium), ceramic, and combination/hybrid materials. Methods of producing an implantable device, such as a load-bearing or non-load-bearing device, such as a bone or other structural implant device (load-bearing), are also presented. Craniofacial, osteogenic and disordered bone regeneration (osteoporosis) uses and applications of devices that include at least one surface that is treated to include a nanoscale or microscale layer or coating of Si—O—N—P are also provided. Methods of using the treated and/or coated devices to enhance enhanced vascularization and healing at a treated surface of a device in vivo, is also presented.
