How well does silicone stick to rubber?

What does stick to silicone rubber? Due to the low surface energy of cured silicones, it is almost impossible to get anything to easily stick to silicone. Because of this special glues and surface preparations are needed to bond cured silicones to another material.

What is the best adhesive for rubber to plastic?

In general, cyanoacrylate instant adhesive is the best choice for bonding rubbers. More commonly known as super glue, this product cures in just seconds and lets you know quickly whether or not the bond will hold.

Can you use silicone as glue?
