High alumina refractory adhesive Type HITAC-4 is developed for bonding low-density insulation materials together without adding significant mass to a fibrous ceramic insulation system. It is a single part water based adhesive that exhibits high strength upon drying. The adhesive contains 73% Al2O3 with a maximum use temperature close to 1430 C (2600 F) and a specific gravity of 1.8 g/cm3. The cement can be applied in a thin layer, is sticky, remains workable for an acceptable period of time, contains no organic material and is stable when applied to most types of low density insulating materials.
