    Cortec BioCorr® ATF Rust Preventative | Rust Corrosion Inhibitor | 55 Gal 

    BioCorr ATF Rust Preventative is an oil-in-water emmulsion rust preventative that is intended for preservation of transmissions in storage and during transportation. BioCorr ATF Rust Preventative provides multi-metal protection and is an excellent environmentally sound alternative to petroleum derived products. This ready-to-use formulation can provide protection for up to two years of indoor storage; or during shipments when combined with VpCI packaging materials.

    Unlike rust preventative oils, this product leaves a virtually undetectable dry film on the surface of the metal. This feature helps to create a clean workplace and prevents material waste. BioCorr® ATF Rust Preventative is VOC free and can eliminate expensive disposal costs associated with oils.

    Cortec is a world leader in rust and corrosion removal and protection. Cortec VpCI® products offer cost-effective and environmentally friendly corrosion protection solutions that are bio-degradable, self replenishing and provide multi-metal protection.
