We buy fresh batches of adhesive every month straight from our manufacturers and direct off the production line so that when they reach you they should be no more than 40 days from manufacture.
This means that if stored correctly the adhesives will have a minimum shelf life of 6 months but can potentially last for up to 10 months.
Once opened adhesives start to degrade around the 1 month mark so it’s recommended you change your adhesive at this point. Never use an opened adhesive beyond 2 months.
