The High-Temp Stove Bright Sealant M230 is an easy-to-use sealant for the maintenance and installation of direct vent appliances such as pellet stoves or gas-burning systems, but can also be used to seal a metal flue for wood and coal burning stoves. In addition it serves as an effective high temp stove gasket adhesive. This sealant resists peak temperatures of around 1100°F but is designed for use with a continuous operating temperature of around 900°F. The sealant dries a charcoal coal color despite appearing black out of the tube. After the product has been applied, air dried, and the cured with heat it can be painted for color matching purposes. The sealant does not contain silicone and must be cured at 200°F For Approximately 1-1/2 Hours. Even when applied to bare metal this product does not promote rust.

Does the product contain chemicals that would preclude its use on a pizza oven? I need to attach a metal front to the brick pizza oven. High mortar cracks in this application due to the differences in metal/brick expansion.

Does the M230 sealant harden when it cures or does it stay flexible?

I need to seal the actual seams ON my metal, wood-burning stove. Will Stove Bright M230 High Temperature Sealant do this job well or do you recommend another product? (I also need a high temperature primer for use before I paint the stove.)
