Introduction: 2-Octyl cyanoacrylate is a high-performance cyanoacrylate organic compound (similar to the common "502 glue"). Due to its unique molecular structure and excellent biocompatibility, it is a core component of current medical biological tissue adhesives (liquid "glue"). It is widely used in industrial and medical fields as a fast-curing adhesive or tissue binder.

Temperature Control: The optimal refrigeration temperature for unopened bottles is 2°C to 8°C. Avoid freezing to prevent damage to the bottle structure. Moisture-proof Sealing: Due to the rapid curing (polymerization reaction) caused by trace amounts of moisture in the air, always wipe the nozzle clean and tighten the cap after each use, and store in the original sealed container. Light and Heat: Avoid direct sunlight and high temperatures (prolonged exposure to temperatures above 25°C will shorten the shelf life). Container Material: High-density polyethylene (HDPE) or glass containers are recommended to prevent material compatibility issues.
