Xylar®coatings are inorganic coating materials capable of operating at extremely high temperatures. Stable to 1200°F (650°C), Xylar is frequently chosen for parts used in jet engines or high-temperature exhaust systems. When used as a base or primer coat, these materials increase salt-spray resistance by several orders of magnitude. Xylar coatings have in common an inorganic, ceramic-metallic bonding agent rather than the organic polymer resins used in Xylan coatings. The ceramic-metallic cornerstone creates coatings which are much harder than their organic counterparts and have the potential for much higher operating temperatures, depending upon the fillers and additives selected for use in the coating. They provide exceptional thin-film corrosion protection and are often top-coated with one of the lubricated Xylan coatings. Xylar can also be used alone when a lubricated surface is not needed.
Xylar coatings are recommended for use in three major application areas:
