Expiration dates and storage of adhesives: The date on the can is the Manufacturing Date, not the expiration date. A tightly sealed can stored in a cool place will last 1-2 years after this date. We recommend #40 be stored in a refrigerator and then left at room temp for a few hours to warm up before mixing. Leaving any solvent glue open overnight will result in evaporation of the solvent base. 


Ridout Plastics provides this information as a reference only not an implied or express fitness of use. As with most chemicals, YOU must experiment with your materials and the adhesives for fitness of use. Many factors can affect the results you achieve, including, but not limited to the ambient air temperature, humidity, cleanliness of bond area, and quality of preparation of bonded edges.
