AC-130 is a high-performance surface preparation for adhesive bonding of aluminum alloys. Data shows AC-130 performs comparatively to the grit-blast silane procedure in the wedge test. The grit- blast sol-gel process has also been shown to perform similarly on the wedge test results as when PAA (Phosphoric Acid Anodize) is applied. The process also provided acceptable wedge test results on titanium and stainless steel alloys when compared to standard controls..
