Check out my photo before you buy! This is Tremco V116W Vulkem brand. The image shows the end of the tube with the words "03/25/21" or an expiration code. Today is the day I received the polyurethane sealant September 11, 2021. That means it expired 170 days or 6 months ago. We have a seller who is listing overdue stock on AMAZON to cover his losses due to too much overdue stock. I am returning it because this sealant uses a slow chemical process to cure. I'm pretty sure it cured pretty well in the tube as it has an expiration date printed on it that says 6 months old. Will buy from a reputable seller that I can trust in the future!
