Pyro-Putty® 653 is a thixotropic paste that can be applied to both horizontal and vertical surfaces in cross-sections up to 1/2″ thick. It can be machined and sanded easily after setting at room temperature for 4-8 hours and curing or exposed in-situ to a minimum of 200 °F for 2-4 hours.
Pyro-Putty® 653 is a chemically inert, inorganic compound that will not decompose at ultra high temperatures. It is also water-dispersible, environmentally safe, and resistant too most fuels, solvents and other corrosives.
Pyro-Putty® 653 is ideal for sealing cast steel casings, housings, pipes, and flanges. It can also be used as a replacement for non-structural weldments and flame spray repairs that otherwise fatigue rapidly at high temperatures. Typical applications include repairing afterburners, boilers, exhaust pipes, furnaces, incinerators, and ovens.
Pyro-Putty® 653 is available from stock in pint, quart, gallon and five-gallon pails. Please contact Aremco’s Technical Sales Department for more information about this advanced material.
