Discontinuation Engineering Bulletin
Semco Pasa-Jell 101 is a blend of mineral acids, activators, and inhibitors.
Semco Pasa-Jell 101 is designed to clean and passivate stainless steel that has started to erode. It is convenient to use in field passivation because stainless steel equipment can be passivated without disassembling.
Semco Pasa-Jell 101 accomplishes the passivation of stainless steel by removing foreign materials and corrosion products that could set up local cells and cause pitting corrosion and by forming an extremely thin but corrosion-resistant adherent oxide film on the metal.
Semco Pasa-Jell 101 can also be used to remove anodized coatings from aluminum. In addition, its consistency is such that it can be used for soft stripping of anodized coatings, thus eliminating the need to mask areas to be welded when large aluminum sheets are to be anodized.
Uses
- For cleaning and passivation of stainless steel.
- For removal of anodized coatings from aluminum.
