Pyro-Putty 2400 is a ceramic and stainless steel filled, high temperature, thermally conductive paste used to bond, seal and repair defects up to 3/8? in cross-section in cast iron, steel and stainless steel components and structures up to 2000 oF (1093 oC). Pyro-Putty 2400 is a single part, thermally shock resistant paste that will not decompose at high temperatures. It is a water-based material that contains no volatile organic compounds. It sets at room temperature and cures in-situ or by heating to 200 ºF for 2-4 hours. It can be machined and painted after curing. Pyro-Putty 2400 can be used to effect seals and repairs in exhaust manifolds, headers, mufflers, catalytic converters in engine applications as well as commercial and industrial high temperature systems such as turbines, incinerators, boilers, ovens, and furnaces.
