ORABOND is a plastic , air setting refractory compound used for laying fire bricks with thin , strong joints: for making refractory mixtures used for hot and cold patching, pointing up cracks , filling holes , building and repairing baffles and for general furnace maintenance work. ORABOND forms a long lasting bond between brickwork.It air sets at normal temperatures.Heat merely increases the strength of this bond and quick temperature changes do not weaken it.
