Tsüanoakrülaat

Tsüanoakrülaat, commonly known as super glue or cyanoacrylate adhesive, is a fast-acting adhesive used for bonding a variety of materials. It is a monomer that undergoes rapid polymerization in the presence of moisture, forming a strong, rigid bond. The polymerization process is an anionic addition reaction. Tsüanoakrülaates are typically clear liquids that harden upon exposure to air. Different formulations exist, varying in viscosity and setting speed. Some common types include ethyl cyanoacrylate, methyl cyanoacrylate, and butyl cyanoacrylate. Ethyl cyanoacrylate is widely available for consumer use, offering a good balance of strength and flexibility. Methyl cyanoacrylate is often used in industrial applications due to its faster curing time and higher temperature resistance. Butyl cyanoacrylate, with its lower toxicity and more flexible bond, is employed in medical applications for wound closure. The adhesive works by forming a chain of polymerized molecules that interlock with the surfaces being joined. It is effective on plastics, rubber, metal, wood, and ceramics. However, it can be brittle and may not be suitable for applications involving significant impact or extreme temperatures. Care should be taken to avoid skin contact, as it bonds rapidly to skin and can cause irritation.
