Product Introduction of 3M Scotch-Weld Composite Surfacing Film AF 191XS
3M Scotch-Weld Composite Surfacing Film AF 191XS is a thermosetting modified epoxy adhesive in film form that provides long-term durability and meets specific challenges for metal and composite solid panels. 3M™ Scotch-Weld™ Structural Adhesive Film AF 191XS offers a lightweight conductive screen for lightning strike/composite surfacing, differentiating it from the AF 191.
3M™ Scotch-Weld™ Structural Adhesive Film AF 191XS provides excellent performance with easy-to-use shop handling properties. While very similar to 3M™ Scotch-Weld™ Structural Adhesive Film AF 191, 3M™ Scotch-Weld™ Structural Adhesive Film AF 191XS offers a lightweight conductive screen for lightning strike/composite surfacing. It is also compatible with multiple substrates and primers. In addition, AF 191XS exhibits excellent pre-bond humidity performance on composite substrates.
Adhesive bonding enables a more lightweight structure because it allows you to use more lightweight composite, as opposed to the metallic materials that were used in previous designs. Structural adhesive films are employed anywhere you are trying to bond metal to composite. This offers good erosion performance while minimizing weight.
Key Features
- Designed for 350°F cure (175°C)
