ZIRCAR Refractory Composites, Inc.: Rigidizer/Hardener

July 29, 2002
ZIRCAR Refractory Composites, Inc. recently announced the introduction of its Al-Hard rigidizer/hardener, which is used to increase the hardness of ZIRCAR refractory sheet products. Al-Hard is comprised of aluminum oxide and phosphoric acid in a water base. Refractory sheet products treated with the rigidizer/hardener are ready for use after drying. When a chemical bond forms, it hardens the fibrous material; the degree of hardening depends on the amount of Al-Hard used. Non-flammable and not affected by freezing, it can be applied by immersing, spraying, brushing or sponging.
