Viscotaq™ Tank Chime Sealing System

A visco-elastic system for protecting the base area of aboveground steel storage tanks from corrosion.

Viscotaq is a viscous elastic synthetic material that remains flexible and tacky during its entire life. As the floor plate of a tank is constantly moving during the filling and emptying process, flexibility and aggressive adhesion is of utmost importance.

The Viscotaq Chime Sealing System is used to prevent water infiltration at the concrete ring wall interface of the tank, a place where corrosion normally occurs. The Viscotaq System can be installed on new and existing facilities, can be painted immediately after installation, and does not interfere with any future paint, inspection, and maintenance programs according to API 653.

The Viscotaq Tank Chime Sealing System comprises Viscosealant, or Viscomastic XHT and Viscotaq EZ Wrap.
