The 100% solids polyurethane coating technology is an excellent alternative to the conventional epoxies that dominate the industry today for lining potable water storage tanks and pipes because it is safer, faster to apply, more economical and offers greater longevity. This paper covers the basic definition and history of polyurethane as well as the wide range of applications in a variety of industries. Next, the paper covers the specific advantages of the 100% solids polyurethane coating systems compared to the conventional epoxies in terms of safety, application, performance and cost. Finally, the paper chronicles several case histories. These examples cover unique aspects involving service conditions, substrates and application conditions.
