Pyro-Putty® 1000 is an advanced, two-part, water-based, ceramic and aluminum filled paste that operates to 1400°F (760°C). It is used to repair defects in cast aluminum manifolds, seal aluminum housings found in infrared ovens and seal sheet metal exhaust stacks found in industrial furnaces and incinerators. It contains no asbestos or volatile organic compounds. It is a two-part powder and liquid system, which is mixed typically to a paste-like consistency, then dispensed into place in cross-sections up to 0.5-in. (13 mm) thick. It sets at room temperature in 16-24 hours and can be cured in-situ or by heating for 1-2 hours at 160°F (70°C).
