ZIRCAR Ceramics’ Alumina-Silica Type AX Moldables are putty-like materials consisting of high-purity refractory ceramic fibers (RCF) dispersed in a sticky, water-based refractory binder. AX Moldables exhibit excellent adhesion and insulation properties and are characterized by their high strength, low shrinkage, and low thermal conductivity up to 1260°C (2300°F).
Type AX Moldable is useful as a hard surface coating on low- density high-temperature materials including insulating firebrick, ceramic fiber board and foams as well as ceramic fiber blankets. It also makes a very effective bonding cement on low-density insulation materials such as ceramic fiber boards or microporous silica materials.
Type AXAL Moldable contains non-wetting agents and is used in the assembly, construction and repair of molten non-ferrous metal transport components.
Non-critical drying of applied material usually results in a hard surface. AX-Moldable has a shelf life of approximately 6 months and should not be allowed to dry out or freeze.
