ZIRCAR Refractory Composites: Alumina Coat
May 7, 2002
ZIRCAR Refractory Composites, Inc. recently announced the introduction of its Alumina Coat, an all-alumina liquid formulation used for hardening and increasing the refractoriness of the surfaces of alumina and alumino-silicate fiber products. The material is composed of high-purity aluminum oxide in a water base. Hardening of the surfaces of blanket and felt insulation improves the resistance to erosion by high-velocity gases and reduces the permeability of gases. In many cases, the tendency of flame burn-through of low-density ceramic fiber insulation can be prevented with a coating of Alumina Coat. Additionally, ceramic papers, including alumina and alumina-silica paper, can be rigidized with the liquid.
