ABOVEGROUND STORAGE TANKS

ABOVEGROUND STORAGE TANKS
- Application of 100% Solids Polyurethane Coatings

A nationally recognized steel tank manufacturer had been using a commercial high solids aliphatic polyurethane coating to coat the exterior of their above ground tanks. Although the high solids system gave a satisfactory finish when cured, it created problems in production. One of the serious problems was the length of time required between coats as well as the time it took the coating to dry, especially at cold winter temperatures. This cut capacity and slowed production considerably. When the tank was coated with the new 100% solids aliphatic polyurethane technology, however, a number of advantages became immediately apparent: only one coat was required to completely cover the tank without a primer; the new coating cured in about 20 minutes at ambient temperature and the tank could be moved out of the painting room very quickly - this allowed them to bring the next tank in for coating quickly; and the new coating dried to a bright and shiny finish which has excellent resistance to UV and weathering.
