• Seals close fitting joints between rigid metal faces and flanges. • The product cures when confined in the absence of air between close fitting metal surfaces. • Provides resistance to low pressures immediately after assembly of flanges. • Typically used as a form-in-place gasket on rigid flanged connections, e.g. gearbox and engine casings, etc. • The thrixotropic nature reduces the migration of liquid product after application to the substrate.
