Storage and Shelf Life:
When stored at the recommended conditions in original, unopened containers, this product has a shelf life of 9 months (cartridge), 6 months (sausage).
The shelf life of polyurethane sealant is related to the temperature and humidity of the environment. The recommended storage temperature is 5-25°C, humidity is <50% RH. It is strictly prohibited that the transportation or storage temperature is over 30°C or the humidity is over 80% RH. And high-temperature container transportation is prohibited as well. In the long-time high temperature and high humidity storage environment, the product is easy to get viscous, extrusion will be deteriorated and shelf life will be shortened.
