Pyro-Putty® 2500 is a ceramic and iron oxide filled, high temperature paste used to bond, seal and repair defects up to 1/4″ in cross-section in cast iron and steel components and structures up to
1600 oF (871 oC).
Pyro-Putty® 2500 is a single part, black-pigmented paste that will not decompose at high temperatures. It is a water-based material that contains no volatile organic compounds and it sets at room temperature and cures in-situ or by heating to 200 ºF for 2-4 hours. It can be lightly machined then painted after curing.
Typical applications for Pyro-Putty® 2500 include repairing and sealing afterburners, boiler casings, castings, heat exchangers, exhaust manifolds, flanges, headers, incinerators, molds, and mufflers. It is available from stock in pint, quart and gallon containers.
