Storage & Shelf life:
The shelf life of GP-0416 stored at 20 ± 4℃ is 12 months from the date of manufacture.
Cool storage at around 12℃ can extend the shelf life.
Long-term exposure above 25℃ will reduce the shelf life.
Prolonged exposure of activators, including cartridges that contain activators, above 35℃ quickly diminishes the reactivity of the product, and should be avoided.
This product should never be frozen.
