Methoxyethyl 2-cyanoacrylate

Methoxyethyl 2-cyanoacrylate

(Methoxyethyl 2-cyanoacrylate) is a high-performance instant adhesive (super glue) monomer. It rapidly polymerizes and cures upon contact with trace amounts of moisture at room temperature. Due to its excellent properties—including low whitening and low odor—it is widely used in precision electronics, jewelry, and other applications requiring high-quality aesthetic bonding.

Storage Instructions

Storage Instructions

Storage of Unopened Products (Long-Term Storage): We recommend storing unopened products in the refrigerator at 2°C to 8°C, where they typically have a shelf life of up to 12 months. Do not store in the freezer, as this may compromise the adhesive’s performance. Storage After Opening
(Daily Use): Do not return to the refrigerator. If glue removed from refrigeration is not allowed to return 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 and away from direct sunlight. After use, wipe any residual glue from the bottle opening with a paper towel and tighten the cap securely.
