Semco Pasa-Jell 107 and 107-M has been discontinued by PPG Aerospace.
Discontinuation Engineering Bulletin
Semco Pasa-Jell 107 and 107-M are mineral acids, activators, and inhibitors blends.
Semco Pasa-Jell 107 is inorganically thickened to permit application in localized areas.
Semco Pasa-Jell 107-M does not contain the inorganic thickener permitting immersion of large surfaces.
Semco Pasa-Jell 107 is designed to provide a balanced ratio of components that will maintain the etch rate’s effectiveness and inhibit embrittlement as long as the total acid content is maintained above 20%.
Bond strength improvement is based on surface activation, which provides a receptive surface for adhesion.
Semco Pasa-Jell 107 and Semco Pasa-Jell 107-M chemically clean and activate the titanium alloy surface to provide improved chemical bonding of the adhesive. Semco Pasa-Jell 107 and Semco Pasa-Jell 107-M leave a clean surface with no trace of residual smut.
Semco Pasa-Jell 107 and Semco Pasa-Jell 107-M are formulated specifically for titanium alloys.
The etch life of Semco Pasa-Jell 107-M is approximately 125 to 250 square feet of surface per quart.
Uses
- To improve the metal bond adhesions of titanium alloy.
