Semco Pasa-Jell 102 are blends of mineral acids, activators, and inhibitors. They do not contain fluorides and can be used in applications where fluorides are prohibited.
Semco Pasa-Jell 102 are designed to clean and passivate aluminum and aluminum alloys. They accomplish the passivation 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 102 can also be used to remove anodized coatings from aluminum, although it does not act as rapidly as Semco Pasa-Jell 101. When spot removing anodized coatings, it will stay in place without running onto adjacent areas.
- For cleaning and passivating aluminum and aluminum alloys.
