  • Publication number: 20070289966
    Abstract: A liner and method of application for use on a metal surface to protect metal structures such as cooling towers, evaporative condensers, and other liquid containing vessels such as tanks from corrosion, leaks, and wear. The liner is an inexpensive apparatus and process comprising a coated metal having a second sealing and bonding layer and a third protective sealing layer. The liner method comprises applying an organic bonding layer onto the galvanized substrate, and applying an elastomeric barrier coating to the bonding layer. The barrier coating material is applied to preseal the seams between adjoining panels assembled to form the basin. The barrier coating is applied to the entire inside of the basin to form a homogenous barrier coating extending out of the basin. The liner edge is isolated from the basin by extending the liner to a point between the basin and an upper section.
