Alseal 220I |
Alseal 220I is a single-component, chromefreecoating 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. 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 1150°F. Although an inorganic coating, it combines thermal stability, excellent adhesion and hardness, along with good flexibility... a property not found in most inorganic 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. Further, the coating formed from Alseal 220I composition offers superb thermal shock 1600°F。
