Fast-Drying Non-Corrosive Anti-Tarnish Silicone Sealant for Copper Doors

Quick-drying/non-corrosive/patina-resistant: This copper door adhesive is a fast-drying silicone sealant designed specifically for the installation and sealing of copper and other precious metal doors. Its chemical inertness ensures it won't cause electrochemical corrosion when in contact with copper, fundamentally preventing the formation of patina. Its fast dry-to-dry time helps improve installation efficiency.
