What is the life expectancy of the mastic sealant used on Flat Panel tanks?

The tanks components (sheets, bolts, gaskets and sealants) are designed to last for the life of the tank (25 to 45 years), depending on the type of coating and tank application. To maximize the life of our tanks our engineers will work with you to understand all the details of your particular application to ensure that the proper sealant is chosen i.e. what product is being stored, what are the operating conditions etc.
