Refractory CoatingPyro-Paint™ 634-AL is a two-part, 99%
alumina-filled, ceramic coating system used to bond, coat and seal refractory
fiber boards and other shapes used in molten metal fluid-handling components
and structures in applications to 3200°F (1760°C). The advanced material helps to prevent
wear and oxidation of refractory components and increases heat reflectivity to
improve thermal efficiency and enable temperatures to ramp up more rapidly.
Pyro-Paint 634-AL exhibits exceptional adhesion to refractory fiberboards as
well as alumina, graphite and ceramic cloth. It is resistant to wetting by most
molten metals, increasing the durability, erosion resistance and reliability of
the underlying structure.
