Alseal HX涂层

　　Alseal HX是一种涂料组合物，用于保护铁合金免受高温热氧化和高温腐蚀。

　　同时为贱金属提供牺牲（阴极）保护。 HX专为应用于

　　标头，提供光滑的表面效果，可打磨成镜面光泽。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
