Pyrosealant™

High amorphous silica content outperforms other high temp sealants as a seal or gasket in severe environments.



Cures at room temperature
Pyrosealant™ forms durable, flexible, vibration-resistant gaskets directly on the flange, and cures to a tack-free state in 10-15 minutes under normal room temperature conditions.

Pyrosealant™ is a heat resistant iron oxide red sealant and gasket-maker material that cures at room temperature into a tough, rubbery solid. It is composed of amorphous silica, polydimethyl-siloxane, iron oxide, and a specially developed curing catalyst to facilitate a moisture- sensitive cure at room temperature within approx: 18 hours.

For best adhesion, Pyrosealant™ should be installed on a clean, dry surface.

Continuous temperature rating of 550°F (287°C)
Due to its high silica content, Pyrosealant™ outperforms other high temperature sealants. It has a continuous temperature rating of 550°F (287°C) and withstands intermittent exposure to 1000°F (538°C). Pyrosealant™ is ideal for outdoor and maintains its flexibility to -65°F (-59°C).

Standard cartridge or custom packaging
Supplied in 10.9 oz (310 ml) caulking cartridges. Custom packaging is also available.
