SEMCO Pasa-Jell 101 and 101-M
for use on corrosion resistant steel, aluminum and aluminum alloys
Use
• For cleaning and passivation of stainless steel.
• For removal of anodized coatings from aluminum.

Description
Semco Pasa-Jell 101 and 101-M are blends of mineral acids, activators, and inhibitors.

Semco Pasa-Jell 101 is designed to clean and passivate stainless steel that has started to corrode. It is convenient to use in field passivation because stainless steel equipment can be passivated without disassembling. Semco Pasa-Jell 101-M does not contain an inorganic thickener, thereby permitting immersion of large parts in tanks of Semco Pasa-Jell 101-M.

Semco Pasa-Jell 101 and 101-M accomplish 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 and 101-M can also be used to remove anodized coatings from aluminum. 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.

Conforms to:
ASTM A380 - Standard Practice for Cleaning, Descaling and Passivation of Stainless Steel Parts, Equipment and Systems.
ASTM A967 - Standard Specification for Chemical Passivation Treatments for Stainless Steel Parts.
