Xylar-aqueous/acidic based aluminum cermet coating having excellent chemical, corrosion and abrasion resistance at extreme temperatures. Many industries like aircraft, aerospace and marine has widely used this coating to protect components from high temperature oxidation ,salt laden atmospheres ,chemicals and abrasives. This grade complies with MIL-C-81751B.This enhances the system performance by retarding the rate of sacrificial anodic protection afforded by Xylar. Fasteners using in oil refineries and related are widely using this coating to have a loner life and thus by protecting the assemblies and supporting service. Coated surface has to be prepared in such a way to have proper conduction to avail a maximum performance of this coating.
