Unless you can get data from the manufacturer stating how the properties deteriorated with age of unmixed material, I would not use it on critical applications. You simply will not know how much strength you may be loosing. I have kept various epoxies around for years after their expiration dates and used them on projects where strength was not an issue. I never had a batch not cure, but I certainly would not interpret that as meaning the batch had obtain full strength.
