PERMOBOND has a shelf life of at least 12 months if stored in a cool (below 25°C), dry place in its original moisture-tight container. The glue should not be stored below 0°C or above 30°C. If the material is kept beyond the recommended shelf life, it is not necessarily unusable. A check should be performed to observe whether the product has not separated, thickened, or shows signs of bacterial degradation (bad smell, discoloration, and low viscosity). To maximize the shelf life of the opened container, ensure that the packaging is closed to create an airtight environment when not in use.
