Cyanoacrylate is a fast-acting adhesive commonly known as super glue. It is a type of acrylic 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, making it ideal for quick repairs. This adhesive is widely used in both household and industrial applications due to its strong bond and ease of use. However, it is important to handle cyanoacrylate carefully, as it can bond skin and eyes quickly, and proper ventilation is recommended during use.
