Diyuk

Restore the Safety and Efficiency of Your Heating System with Professional-Grade 1500°C Sealing Power.When the integrity of your wood burner or flue is at stake, standard sealants simply aren't enough. The extreme thermal shock, corrosive flue gases, and direct flames of a solid fuel fire demand a specialised solution. Our High Temperature Silicone Sealant (1500°C) is a heavy-duty, silicate-based compound.Most ""heat resistant"" silicones sold for automotive use fail at 300°C. They turn brittle, peel away, or degrade into a gummy mess, risking smoke leaks. Our formula is different. It is rated for 1500°C.Versatile & Robust ApplicationDesigned for static (non-moving) joints, this sealant offers unrivalled adhesion to the materials found in your hearth.Flue Systems: Seal the gap between the stove spigot and the flue pipe, or bond flue liners to register plates.Firebox Repairs: Fill cracks in firebacks, re-set loose firebricks, or seal gaps in pizza ovens and chimineas.Assembly: Ideal for cementing ceramic rope or sealing stove glass into cast iron doors.We understand that aesthetics matter. The sealant applies as a smooth black paste, allowing for precise tooling. Upon firing, it cures to a matte dark grey/charcoal finish that blends naturally with cast iron and matt black flue pipes, leaving your installation looking clean and professional.Application Masterclass for Best Results:To ensure a crack-free cure, ensure all surfaces are clean and free of rust. Crucial Tip: If applying to porous brick or clay, lightly mist the surface with water first to prevent the sealant from drying too quickly.After the final solidification, slowly heat the sealant up to +250 °C. As the result of heating, the mass will turn dark grey and become extra-hard.Technical Specifications:Max Temp: 1500°CCure Type: Rigid / HardColour: Black (Paste) -> Dark Grey (Cured)Size: 310ml Cartridge (Fits standard gun).
