Description
Rust Preventive Oil (RPO) is a type of protective coating designed to safeguard metal surfaces from corrosion and rust, primarily during storage, transportation, or idle periods. RPOs are essential in the metalworking industry, ensuring that machined components, parts, and machinery maintain their quality after processing and before final assembly or use. RPOs are generally based on highly refined mineral oils combined with a complex additive package. This package includes corrosion inhibitors (such as sulfonates, which create a chemical barrier) and film-forming agents.
