A high-temperature dip-applied coating composition with aluminum powder in an inorganic binder. Provides sacrificial corrosion protection to temperatures up to 1100°F (593°C) and heat oxidation protection to temperatures as high as 1600°F (871°C). Can be cured as low as 350°F (177°C). Not suitable for use on mild steel substrates.  Alseal 585 exhibits an increased viscosity for dip application.
