Cortec offers two rust preventatives—BioCorr and VpCI-325—that have been approved for weldable applications through EHS and mechanical destructive testing at a heavy equipment manufacturer.
BioCorr is for a virtual undetectable dry film rust preventative that does not have to be removed before further component assembly and processing. BioCorr is a USDA Certified Biobased Product that contains 64 per cent USDA certified biobased content, offering a double advantage compared to messy petroleum-based products made from non-renewables.
For a more traditional rust preventative that leaves behind an oily film, VpCI-325 is another weldable option. The tenacious film of VpCI-325 displaces water and inhibits corrosion. Rather than being completely solvent-based, VpCI-325 has a partial vegetable oil base, improving its environmental profile via a biobased, biodegradable raw material.
