Abstract
Compositions are described for protecting a metal surface against corrosion. The composition includes a corrosion-inhibiting particle. The corrosion inhibiting particle may be usable in an epoxy resin-based coating or an olefin resin-based coating. The particle may include a core and a protectant. The core may include a water soluble corrosion inhibitor. The protectant may be disposed on at least a portion of a surface of the core and may be covalently or ionically bonded to a thiol group of the corrosion inhibitor. The protectant may be configured to reduce reaction between the core and the epoxy resin or the olefin resin.
