Semco 222555 Pasa-Jell 105 Cleaning Compound - Quart

For optimum results, the surface should be degreased with a solvent followed by either a wet or, preferably, a dry blast with a fine grit of 250 or 320 aluminum oxide to remove all corrosion products and to condition the metal surface before application of the Semco Pasa-Jell product. Where blasting is not practical, the surface can be sanded lightly with aluminum oxide coated abrasives.

Apply a layer of Semco Pasa-Jell 105 to localized areas with a polyethylene, polypropylene or fluorocarbon bristle brush immediately following the abrasive treatment and allow it to stand for about 15 minutes. The Semco Pasa-Jell product should then be rinsed off with cool tap water and allowed to dry at room temperature.

For immersion treatment of large metal surfaces, use Semco Pasa-Jell 105-M in tanks.

Note: Tank linings for Semco Pasa-Jell products should be made of polyethylene or unplasticized polyvinyl chloride.

It is important that the part and the Semco Pasa-Jell 105-M tank solution be held below a temperature of 100° F. This also applies to any tap water rinsing. Treated parts should be dried with cool air prior to priming.

The time limit for the application of primer after rinsing should be held to a minimum, preferably not in excess of one hour, because there is a decay rate of the surface activity. The maximum benefit can be derived by priming the surface soon after the Semco Pasa-Jell treatment.

Storage

Semco Pasa-Jell 105 and 105-M have a storage life of one year without significant loss of activity when stored in a cool, dry area in the original, unopened containers.
