Yes, super glue (cyanoacrylate) works well on rubber for many repairs, forming a fast, strong bond, especially for non-flexible items or quick fixes, but it can be brittle; for flexible or high-movement parts (like shoes), specialized flexible glues (like rubber cement or silicone) are often better, while gel formulas or toughened CAs offer more flexibility than liquid super glue, according to Selleys, Loctite, and Aron Alpha.
Cyanoacrylate, also called "crazy glue" or "super glue," is a good place to start when adhering rubber because it's a great catchall for many substrates. Cyanoacrylate adhesive is an acrylic resin in which the main ingredient, cyanoacrylate, is an acrylic monomer that transforms to a plastic state after curing.
HDPE (high-density polyethylene) is a material that superglue does not stick to at all. You can find sheets of it at hardware stores and online retailers such as Amazon.
Epoxies- When bonding rubber to plastic or another material, epoxy adhesives also tend to be a good choice. Epoxies are known for their great strength, and they effectively allow you to bond rubber to plastic, metal, or glass. Silicones- For smaller projects, fast-curing silicone compounds are another option.
It typically cures in seconds to minutes, depending on environmental factors such as humidity and surface type. However, the full dry time usually takes around 24 hours to allow the adhesive to completely set and reach its maximum bond strength.
This may surprise you, as rubber seems like a material that would be difficult to bond. However, super glue is a high strength, versatile adhesive that can be used on a whole range of materials, including wood, metal, ceramic, and of course rubber.
If the project is stored in ambient conditions, it should be a permanent fix. If the project is stored outside or in an area with temperature or humidity swings, bonds can degrade. Just like anything else, the quality of the super glue formulation can make a difference.
Silicone rubber can be difficult to bond, due to the low surface tension which means that glue cannot normally wet it and provide adhesion. But there are some good alternatives: 1. primer + cyanoacrylate (quick glue).
Will Gorilla Glue bond plastic/vinyl/rubber? Gorilla Glue will work well on many types of plastic; however, we do not recommend for use on polypropylene (PP) or polyethylene (PE) plastics or any type of rubber with high oil or plasticizer content.
Using Adhesives With Rubber Seals and Gaskets
While super glue works with most common materials, avoid using it with cotton, wool, or items that will be placed in a microwave, oven, or dishwasher. Remember that super glue is generally not food safe. It can be difficult for adhesives to bond with plastic because of its smooth texture and low porosity.
First, if you're working with heavier materials or projects that require a long-lasting bond, such as assembling furniture, fixing a broken outdoor pot, or repairing a wooden chair, Gorilla Glue is probably the better choice.
Blot the glue with acetone or rubbing alcohol and let this substance break down the glue. Clear away with a damp cloth.
Rubber to rubber bonding
To assemble two pieces of rubber, two options are available: Use a "super glue" type cyanoacrylate or neoprene glue type "contact glue". Cyanoacrylate glue offers the advantage that a small amount is enough to glue rubbers almost instantly.

Gorilla Clear Grip® can be adhered to many surfaces including: Wood, Metal, Stone, Ceramic, Glass, Plastic*, PVC, Brick, Concrete, Foam, Paper, Rubber, Fabric, and Laminate. *NOTE: Not recommended for use on polystyrene, polypropylene or polyethylene products.
Superglue is indeed waterproof, but not for extended periods of time. For fixing objects that come into occasional contact with water, superglue will hold its bond. But if the object is submerged for a lengthened period of time the bonds will weaken.
The most commonly used glue for rubber bonding is cyanoacrylate adhesive (i.e., super glue). It is often considered the best glue for rubber since it quickly forms a strong bond between substrates.
Here are some examples: Too smooth and non -porous surfaces : Polyethylene (PE) And Polypropylene (pp) : These are plastics often used in everyday objects such as bottles and packaging.
Gorilla Super Glue has been engineered to achieve excellent results on difficult to bond substrates. It is formulated to bond a wide range of ,materials including most plastics, metals, elastomers (vinyl/rubber), wood, and porous surfaces.

Super glue can easily be removed from skin or most surfaces with warm soapy water, or for faster results with acetone.
