Cyanoacrylate Adhesives (Super Glue)
Check Out Our Cyanoacrylate Super Glue Adhesives
Cyanoacrylate adhesives (CAs), also commonly called super glues or sometimes instant adhesives, are known for their fast bonding and great strength. They work well with many more difficult substrates like metals, plastics, and glass. Because of these properties, cyanoacrylate adhesives can be used in a variety of structural bonding applications in various industries.
At Gluegun.com, we carry a diverse selection of cyanoacrylate glues from top brands like Loctite, ASI, and Infinity Bond. Whether you are looking for a cyanoacrylate adhesive that is low viscosity, low bloom, or non-sag, we have the product for you.
If you have questions about which product is the best cyanoacrylate glue for your application, we want to help. Contact us today and you can speak with an adhesive expert.

Common Questions About CA Adhesives
The viscosity of a cyanoacrylate super glue refers to the thickness of the adhesive and is usually referenced in centipoise (cps). Thinner super glues are good for getting into tight places and covering substrates while thicker super glues can help with gap filling. Below is a brief reference for viscosity.
- 1-5 cps: like water
- 50 to 100 cps: like motor oil
- 2,500 cps: like honey
- 50,000 cps: like Ketchup
Surface insensitive cyanoacrylates are formulated for extremely fast curing, even by super glue standards. They also bond to a wide range of surfaces including wood, plastics, metals, and glass. Surface Insensitive super glue adhesives are one of our favorite choices for general purpose use because of their set speed, strength, and versatility.

Toughened super glue, sometimes called rubber toughened, is formulated to offer impact and shock resistance. Toughened cyanoacrylates typically have a more flexible bond and hold up under high and low temperatures. They are also often better for outdoor conditions when exposed to a lot of moisture or humidity.
Cyanoacrylate accelerators can be applied on substrates before super glue is applied, or in some cases afterwards, to make the adhesive cure faster. They are particularly useful for substrates that are hard to hold in place, high volume applications, or slower set time cyanoacrylate adhesives (like toughened super glues).We have a complete line of adhesive accelerators to help speed up your next super glue bonding application.
The best cyanoacrylate adhesive for your application will depend on a few different factors such as the materials being bonded, the set time, and more. Below are a few of our recommendations based on specific properties you may be searching for.
