Abstract
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.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from the content, the content of which is incorporated herein by reference. technical field [0003] The present disclosure relates to methods, compositions and reagents for inhibiting corrosion in various substrates, such as metal substrates. The present disclosure also relates to corrosion inhibitors comprising organometallic polymers such as metal organic frameworks (MOFs), including compositions and methods comprising MOFs for inhibiting corrosion in metal substrates. Background technique [0004] Protecting substrates, such as metal substrates, from atmospheric corrosion presents difficult challenges and is of great economic importance. The many metallic substrates that require protection from corrosion typically include aluminum alloys used in the aerospace industry, ferrous metals, zinc metals and alloys used in protective coatings. [0005] It is well known that pigmentary gr...
