High Alumina Refractory
Adhesive Type HITAC-4
GENERAL INFORMATION
ZIRCAR High Alumina Refractory Adhesive Type HITAC-4 is a single part water based high alumina containing adhesive. Containing ~73% Al2O3, it is totally inorganic and has a maximum use temperature of approximately 1425C (2597F).
Specifically developed for bonding low-density fibrous ceramic insulation materials together without shrinking and adding significant mass, it forms a strong bond upon drying. It is possible to create a cylinder using Alumina-Silica Blanket Type ASB-2300 (or ASB-2600), Silica Rigidizer Type SI-RIG and HITAC-4 Adhesive, that does not degrade after firing to 1300C, as illustrated in the photo on the right.
HITAC-4 is a white, creamy sticky material that remains workable for an extended period of time. Thin layers of it can be applied with a brush, paint roller or sprayer. Once fired to 425C (800F) HITAC-4 exhibits a bond that is stable to re-exposure to water or humid conditions and exhibits high dielectric strength.
This new adhesive is amazingly stable and can be applied to most types of porous low density insulating materials.
