3M™ Aerospace AC-131 BB Blue BMS10-128A Type I, Class B, Grade A Spec Surface Pre-Treatment - Quart Kit

AC-131 is a high-performance non-chromated conversion coating for applications on aluminum, nickel, stainless steel, magnesium and titanium alloys. The AC-131 conversion coating is appropriate for parts subsequently finished with epoxy-based and polyurethane-based organic coatings. It is a gradient coating that promoted enhanced adhesion as a result of the chemical interaction at the inorganic metallic interface on one side of the AC-131 coating and the organic primer on the other side. AC-131 provides an excellent environmentally friendly alternative to the high performance requirements for modern coating systems. This process is valid on alloys in the following forms: sheet, plate, foil, forging, and honeycomb core.
