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
