Pyro-Putty 653 is an inorganic, single-part, ceramic and metal-filled paste that bonds tenaciously to cast iron, steel and stainless steel. It withstands continuous operating temperatures and rigorous thermal cycling to 2000°F (1093°C). The high-temperature repair compound is ideal for sealing defects in cast steel casings, housings, pipes and flanges. It can also be used as a replacement for non-structural weldments and flame spray repairs. Typical applications include repairing furnaces, ovens, gas manifolds, afterburners, boilers and incinerators.
