Flame Seal TB Thermal & Ignition Barrier Fire Retardant Coating 50 Gallon Pail FSTB-50


Flame Seal-TB is a two-part coating designed for use as a fire retardant coating over Spray Foam Insulation for interior applications.

The product can be applied over most foam brands. Please check certification information for details. The product has been certified as both Thermal and Ignition Barriers. When Flame Seal-TB is exposed to fire or extreme heat, a protective layer of Carbon Foam develops and prevents the fire and heat from transferring to the foam insulation. Flame Seal-TB comes in White, “Light” “Medium” and “Dark” Grey and Black.
