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.
