New tool and die rust preventative protects molds from corrosion at less cost than conventional methods

May 21, 2019

Cortec Corp. (St. Paul, MN), a specialist in corrosion control technologies, has introduced EcoAir Tool & Die Rust Preventative to meet the needs of mold, tool and die manufacturers and end users. The liquid rust preventative comes in a non-flammable spray can that is easier to use than traditional greases and shipping oils to protect tooling assets and tool steels during shipping, storage and transport. It is also relatively safer to store than traditional highly flammable aerosols, said Cortec.

Cortec tailored the product for a large midwestern U.S. tool and die manufacturer that wanted to eliminate any possibility of corrosion on a 40,000 pound (18,144 kg) Class A plastic injection mold during its five- to six-week shipment by boat to Europe. By packaging an effective vegetable-oil-based rust preventative in an EcoAir spray can, Cortec was able to deliver a cost-effective solution while providing protection of this vital and expensive customer asset.

The customer was so pleased with the results that it requested that all molds be shipped in the same manner going forward.

EcoAir Tool & Die Rust Preventative was sprayed on the internal surfaces of the mold maker’s two-cavity automotive interior P20 plastic injection mold prior to shipment. This provided corrosion protection, as well as water displacement and cleaning properties for any process-related fluids remaining on the mold.

The mold successfully reached the European client with no corrosion issues. The client was pleased that EcoAir Tool & Die Rust Preventative did not need to be cleaned off the mold and requested that all molds be shipped in the same manner going forward. In addition to achieving a successful delivery, the U.S. mold maker also benefited by cutting tooling protection costs approximately in half compared with traditional greases and oils. Unlike EcoAir Tool & Die Rust Preventative, traditional rust preventatives must be cleaned off the mold with solvent-based removers. This increases labor and hazardous waste disposal costs, while exposing workers to additional health concerns.

EcoAir Tool & Die Rust Preventative is specifically designed for all similar tool and die applications and can also be used to clean grease, oils, adhesives and water deposits off metal surfaces. The product preserves all types of carbon or alloy-based steel tooling, molds, fixtures and dies for up to 24 months indoors.
