Storage:
The components have to be stored in tightly sealed and dry original containers in an environment at 6~35°C;. Under these conditions, the shelf life will correspond to the expiration date stated on the label ( normally 12 months). After this date, the product may be reanalyzed to confirm if it validates yet. Partial emptied containers should be closed tightly immediately after use.
