Methoxyethyl 2-cyanoacrylate is a high-performance instant adhesive (super glue) monomer. It can rapidly polymerize and cure at room temperature with trace amounts of moisture. Due to its excellent properties of low whitening and low odor, it is widely used in precision electronics, jewelry, and high-requirement surface bonding applications.

Unopened storage (long-term preservation): Refrigerate at 2°C to 8°C; shelf life is typically up to 12 months. Do not store in the freezer, as this may damage the adhesive's properties. After opening (for daily use): Do not return to the refrigerator. If the adhesive taken from the refrigerator is not brought to room temperature, moisture from the air will easily condense inside the bottle. Store at room temperature in a cool, dry place out of reach of children, avoiding direct sunlight. After use, wipe the bottle opening clean with a paper towel and tighten the cap.
