Coatings For Industry, Inc. Alseal HX

Alseal HX is a coating composition formulated for protecting ferrous alloys from both high temperature heat oxidation and at the same time offer sacrificial (cathodic) protection to the base metal. HX was formulated especially for application to headers, providing a smooth finish that may be burnished to a mirror shine. Because of its high temperature capabilities, it offers excellent protection when exposed to cyclic high temperature and corrosive salt environments, continuing to provide sacrificial properties at temperatures to 1150F. Although a ceramic coating, it combines thermal stability, excellent adhesion and hardness, along with good flexibility... a property not found in most ceramic coatings. As mentioned above it offers salt corrosive protection to 1150°F. At about 1200°F. The aluminum oxidizes to a point where it no longer provides its excellent sacrificial properties, however, it will continue to offer excellent heat oxidation continuously to 1600°F. and in some cases, depending on metal substrate, has offered heat oxidation protection to 2200°F.
