Pumpable Ceramic Caulk is a 2300°F ceramic fiber, putty-like consistency material, especially formulated for pumping with special equipment. It is usually used for pumping behind existing hot face linings for insulating purposes; however it can be used to fill small voids and thin cracks.

Pumpable Ceramic Caulk is a light weight material with very low thermal conductivity, and therefore a good insulator. It dries to a firm, board-like consistency, for good sturdy integrity. Its ability to compress makes it ideal for expansion joints, and for filling contraction cracks. In addition it is used in contact with molten aluminum.

Although normally used as a backup material for hot spots, as mentioned above, when used as a hot face material, the Pumpable Ceramic Caulk has excellent thermal shock resistance, and can be dried or put into service immediately with no pre-heat required, with the exception of direct molten metal contact. Then the Pumpable Ceramic Caulk should first be thoroughly dried, and fired, to remove all mechanical water the entire depth of the material, to avoid dangerous steam explosion.
