Rust preventatives based on sodium calcium or barium sulfonates are commonly employed by manufacturers of metal products to protect their products from a variety of corrosion pathways. Although the films are nearly imperceptible the protection they provide can last several months to a year in covered environments. Historically barium sulfonate-based rust preventatives have been touted as superior products as compared to other alkali metal sulfonates. These barium-based products however have come under close scrutiny in recent years from a regulatory standpoint. Even with environmental regulations tightening there has been a reluctance to switch from barium-based products by the manufacturing segment due to a perceived performance advantage. Accelerated testing methods have been employed to demonstrate that calcium- based rust preventatives can provide equal or better performance than barium-based products. Performance of the materials was measured against industry standard controls.
