Coating System

Pyro-Paint™ 634-AS-1 is an alumina-based, fiber-reinforced ceramic coating system used to bond, coat and seal refractory fiberboard used in the construction of infrared heaters and molten-metal handling components in applications up to 2300°F. It is used to encapsulate and secure heating elements and ceramic cloth to refractory boards in the construction of infrared heaters. Pyro-Paint™ 634-AS-1 exhibits exceptional adhesion to refractory fiberboard, graphite and ceramic cloth and paper, and it is resistant to wetting by nonferrous molten metals.
