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. Tests have been conducted using low carbon steel alloys. There was no loss of weight after several weeks continuous exposure at 1000°F. After exposure to 5% salt spray for 1000 hours, there was no evidence of corrosion. Further, the coating formed from Alseal HX composition offers superb thermal shock resistance. The coated metal will not crack, spall, or fail after shocking from 1100°F. to room temperature repeatedly. Surface Preparation Special care must be exercised in the preparation of the surface for all high quality, premium performance coatings. 1) Degreasing. All oil, grease and other organic deposits must be removed by suitable degreasing operation or by heating parts to temperature sufficiently high to facilitate removal. 2) Cleaning and Roughening. All old coats, mill scale, rust, or other tightly adherent deposits must be removed by a method such as dry grit blasting or vapor blasting. Grit blast, using clean aluminum oxide AL2 O3) grit, is the recommended cleaning procedure which is necessary for maximum adhesion to steel, although other abrasive methods may be satisfactory由于其耐高温能力,它提供了出色的保护,当暴露在循环高温和腐蚀性盐的环境中,继续在温度1150提供牺牲性能* F。尽管陶瓷涂层,它结合了热稳定性,优异的附着力和硬度,以及良好的柔韧性......一个属性不是在大多数陶瓷涂层找到。如上所述,它提供了盐的腐蚀防护1150F。在约1200 F的铝氧化成一个点,它不再提供其优异牺牲性能,但是,它会继续不断地提供优良的热氧化1600 F ,在某些情况下,根据金属基板,提供了热氧化保护到2200F

从HX3200组合物形成的涂层提供了极好的抗热震性。该涂层的金属不会开裂,剥落,或反复后令人震惊的失败来自1100F到室温。
