3M Surface Pre-Treatment AC-131 is a high-performance conversion coating for applications on aluminum, nickel, and titanium alloys. This process is valid on alloys in the following forms: sheet, plate, foil, forging, and honeycomb core. The AC-131 application is applicable for parts subsequently finished with epoxy-based and polyurethane-based organic coatings.

AC-131 provides an excellent solvent-free alternative to achieve the high performance required in aircraft paint applications. The current surface preparation technique such as Alodineģ provides acceptable surfaces for coating applications. However, the alodine process produces significant amounts of hazardous waste.

When used with the leading organic primers and topcoats, 3M AC-131 Pre-Treatment provides an economical and environmental alternative to more costly and hazardous processes. 3M AC-131 Pre-Treatment provides equivalent or better wet and dry adhesion performance to that of many of the other surface preparation techniques available. This is true of both OEM and repair/repaint (scuff and sand) applications. 3M AC-131 Pre-Treatment is simply applied to surfaces either by brush, dip or spray on at ambient drying conditions.

Surface Preparation
3M Surface Pre-Treatment AC-131 may be applied after cleaning to a ?water-break free' surface. Alkaline cleaning will usually provide a ?water-break free' surface. Chemical etching and deoxidizing is generally not required. Manual deoxidation can be accomplished by either Scotch-Brite pad abrasion or sanding with #180 grit or finer aluminum oxide sandpaper.
