Designed for static, high-heat applications where standard silicone sealants fail, Würth Furnace Putty 1000 forms a dense, non-elastic, rigid joint resistant to combustion flue gases, condensates, oils, and fats.
Key Features & Benefits
Extreme Heat Resistance: Withstands severe temperature environments up to 1000°C.
Ready to Use: Pre-mixed in a standard 310ml cartridge for direct, mess-free dispensing with a standard caulking gun. No manual mixing or stirring required.
Non-Sedimenting Formula: Stable consistency during storage ensures long shelf life and consistent application without material separation.
Solvent-Free & Silicone-Free: Safe, low-odor curing process that won't release harsh emissions or degrade nearby sensitive components.
Chemical & Flue Gas Resistance: Resistant to flue gases, condensates, oils, fats, and general household cleaners.
Paintable Finish: Can be overpainted once fully cured to match surrounding aesthetics.
