I want to glue a piece of silicone to metal but I am unsure what glue I would need. It is difficult to bond, and the only adhesives which adhere well are silicone based adhesives and cyanoacrylate adhesive after the silicone … To glue silicone rubber. Clamp the items with the C-clamps to hold them, if you desire. Our Process uses the laws of chemistry and the principles of Physics to create bonds. Household projects often involve affixing one item to another item securely with glue. With elastomers, pressure effectively increases the surface area area available to bond. When the bond must be tight and secure, use the right adhesive designed to work properly with the materials. Apply the glue in a well-ventilated area with temperatures between 70 and 85 degrees Fahrenheit. You want a near white finish or steel or polished surface for aluminum and other metals. Other materials such as flourosilicone, urethane, neoprene, millathane, EPDM & natural rubber … By sanding the area, you are giving the glue a better chance of strongly adhering to the aluminum. Apply a bead of the SI Structural Adhesive to the seam between the surfaces. The first time we bonded a poly (a polyurethane bumper cover), we believed, but we had been working with polymers for years. Don’t glue silicone rubber, bond silicone rubber. Silicone is a rubber-like elastomer with high-temperature resistance. But we did not know if the Process worked every time.
