On some kinds of rubber, hot glue adheres effectively. Unfortunately, it might not be practical with plasticizers and rubbers with greater oil content. Rubbers with smooth, slippery surfaces, like silicone rubber, will also not adhere well to hot glue. Super glue is the ideal adhesive for rubber. Cyanoacrylate serves as the primary adhesive component of this acrylic resin. The cyanoacrylate starts to build up and produce a solid bond in minutes. Cyanoacrylate changes into a plastic state after curing.
