The glue PASCOFIX should be stored on a cool, dark and dry place. The best way to enlarge the shelf life is: put the glue together with a bag of Silica-gel into an empty jar of jam (if you don’t have Silica-gel you can also use 2 tablespoon full of salt or rice). Put the jar for storage into the fridge. Before you use the glue again take it out of the fridge and wait till the glue has room temperature.
