Etyylitsüanoakrylaatti

Etyylitsüanoakrylaatti is a chemical compound with the formula C6H7NO2. It is an ester of cyanoacrylic acid and is a colorless liquid with a pungent odor. Etyylitsüanoakrylaatti is primarily known for its use as a primary component in cyanoacrylate adhesives, commonly known as super glues or instant glues.

The rapid polymerization of etyylitsüanoakrylaatti is initiated by weak bases, such as moisture present on surfaces. When a thin layer of the adhesive is applied between two surfaces, the trace amounts of water or other nucleophiles in the air or on the surfaces trigger a rapid anionic polymerization reaction. This results in the formation of long polymer chains that create a strong bond between the surfaces.

Due to its fast curing time and strong adhesive properties, etyylitsüanoakrylaatti finds applications in various industries. It is widely used in household repairs, crafting, and in some industrial assembly processes where quick bonding is required. In medical settings, medical-grade cyanoacrylates, which may include etyylitsüanoakrylaatti or similar compounds, are used as tissue adhesives for wound closure, surgical procedures, and to seal blood vessels. These medical formulations are sterilized and designed for biocompatibility.

While generally considered safe when used as intended, etyylitsüanoakrylaatti can cause skin and eye irritation. It can bond skin rapidly, requiring careful handling. Inhalation of vapors may also cause respiratory irritation. Proper ventilation and personal protective equipment are recommended when working with this chemical.
