Apply the glue to both the rubber and metal surface in a thin layer. Why is the United Silicone solution better?This answer is not merely the use of a uniquely sticky adhesive or glue. When this technique is used in conjunction with the Bonding Poly Process, the silicone will be covalently bonded. Spray one of the silicone rubber surfaces … Full strength may take up to a month. The E6000 stuck to the metal really well, but it peeled off the silicone rubber potholder I was trying to stick it to … Warm the silicone rubber surface with a hair dryer or heat gun. They wont’ fall apart. Rough the surface of silicone rubber with sandpaper or steel wool. With elastomers, pressure effectively increases the surface area area available to bond. Hunker may earn compensation through affiliate links in this story. Spray a solvent based Activator/Accelerator (AA) on either the silicone rubber or metal. Use sandpaper to rough the silicone rubber then clean the surface with a soft cloth. The key to bonding any type of silicone is applying extra firm pressure for fifteen seconds, when the two surfaces are brought together. By temperature, about 120 degrees F. Very firmly Firmly press the two surfaces together for at least 15 seconds. It failed completely on silicone rubber when I tried to glue it to a weightlifting plate.
