FIBER HARDENER
FIBER HARDENER
32 oz. (946ml) A high concentration, large particle size alumina sol for superior rigidizing of refractory fiber shapes or boards. Larger particle size and low viscosity absorbs rapidly and deeply for thorough rigidizing, even of thick shapes of two or more inches. It has less tendency to migrate to the surface when drying, resulting in a more uniform product. Completely cristobalite free at use temperatures below 2200 degrees F. Water soluble. Thin if desired. Dry at 250 degrees F (121 degrees C) or above to obtain Thermal Set.
