Cyanoacrylate is a fast-acting adhesive commonly known as super glue. It is a type of synthetic resin that bonds quickly to various surfaces, including plastic, metal, and wood. When exposed to moisture in the air, cyanoacrylate undergoes a chemical reaction that causes it to harden, creating a strong bond. This adhesive is widely used in both household and industrial applications due to its ease of use and effectiveness. It is often found in products like medical adhesives for wound closure and in crafting for quick repairs. However, it should be handled with care, as it can bond skin and eyes rapidly.
