Cortec biobased rust removers are an alternative to sandblasting and other forms of mechanical rust removal in restoring equipment and components to a better condition. Rust can take place after months or years of shipping or storing metals, or within minutes of a part rolling off the assembly line.
VpCI-422 is a liquid product ideal for use in dip tanks. VpCI-423 is a gel version for use on vertical surfaces or other areas where the rust remover needs to cling. These products remove a significant amount of rust in a half hour. If faster rust removal action is desired, opt for the non-biobased VpCI-426, available in liquid or gel form. All three formulas can be used to remove oxides from iron, steel, and yellow metals.
VpCI-422 and VpCI-423 are relatively easy and safe to use due to their lower acidity and large percentage of common food-industry ingredients. Both products contain 91% USDA certified biobased content and are National Science Foundation (NSF) registered as A3 acid cleaners in the NSF Nonfood Compounds Registration Program.
