Thermbond 7200 Series can substantially reduce the cost of most furnace repairs through its ability to provide consistent properties regardless of installation method. It can be mixed with water for casting or pumping; mixed with 7200 Liquid for gunning or ramming; or mixed with 7200 Accelerator for shotcreting. Only two different liquids are required for all five major installation methods, and the amount of liquid is roughly 5% by volume of the dry mix. Thermbond 7206 is a mullite-based material, and Thermbond 7206-N is non-wetting to molten aluminum. Thermbond 7229 is a mullite-based material with a 20% SiC addition, and Thermbond 7229-N is the same formulation in a version that is non-wetting to molten aluminum. Depending on the installation configuration, thickness, lining condition and geometry, it can be fired in at up to 392°F (200°C) per hour with no holds.
