How can I extend the shelf life of MS sealant?
To extend the shelf life of MS sealant, you can refer to the following methods:

Strictly control storage temperature: MS sealant is temperature-sensitive and should be stored between 5°C and 25°C. Excessively high temperatures accelerate chemical reactions and volatilization of the glue’s components, while excessively low temperatures can also affect its performance. Also, avoid direct sunlight and heat sources to prevent abnormal temperature fluctuations.

Maintain a dry and ventilated environment: Humid air increases the moisture content in the glue, affecting its adhesion and curing properties. Therefore, store the glue in a dry, well-ventilated area. If necessary, place a desiccant in the storage area or store it in a moisture-proof container to protect it from moisture.

Ensure the glue packaging is sealed: When the glue is unopened, inspect the packaging for damage. Leaks can cause premature curing. After opening and using, be sure to tighten the cap immediately to prevent air from entering. If the bottle cap isn’t airtight, you can transfer any remaining glue to a smaller, well-sealed container to minimize its exposure to air.

Prevent glue contamination: The purity of the glue affects the bonding effect. When storing, prevent dust, oil, and other impurities from entering the glue bottle. For example, you can install a seal or filter around the bottle cap. Also, avoid handling the glue with uncleaned tools during use.

Reduce unnecessary openings: Every time you open the bottle cap, the glue comes into contact with air. Therefore, use only the amount of glue you’ll need. Avoid opening the bottle cap frequently to minimize the risk of the glue being contaminated by external factors.
