ZIRCAR cements and rigidizers are useful for bonding, repairing, coating or strengthening low density fibrous alumina and alumina-silica thermal insulation materials. Cements are viscous liquids with the consistency of house paint. Rigidizers are milky aqueous solutions. They dramatically increase the hot strength and dimensional stability of materials and find use to 1650°C (3000°F).

Alumina Cement Type AL-CEM
Type AL-CEM Alumina Cement is a high purity alumina bonding agent used for bonding ZIRCAR® fibrous ceramic products to themselves, and as a coating cement to improve the hardness and oxidation resistance of substrates.

Alumina Rigidizer/Hardener Type AL-R/H
Type AL-R/H Alumina Rigidizer/Hardener is a single part water based colloidal suspension of alumina hydrate. Mainly used for rigidizing and hardening the surfaces of ZIRCAR® fibrous ceramic products it also finds use as a coating agent and binder.

Alumina-Silica Cement Type AS-CEM
Type AS-CEM Alumina-Silica Cement is a high temperature resistant cement useful for creating a hard coating on the surfaces of ZIRCAR® Alumina-Slica fibrous ceramic products or other porous insulating Materials. It has useful properties to 1260°C (2300°F).

Silica Rigidizer Type SI-RIG
Type SI-RIG Silica Rigidizer is a single part water based colloidal suspension of colloidal silica. It is principally used for rigidizing and hardening the surfaces of ZIRCAR® fibrous ceramic products, but is also widely used as a coating agent and binder.

High Alumina Refractory Adhesive Type HITAC-4

High Alumina Refractory Adhesive Type HITAC-4 is a single part water based high alumina containing adhesive. Specifically developed  for bonding low-density fibrous ceramic insulation materials together without shrinking and adding significant mass, it forms a strong bond upon drying.
