Coating technologies for bridges has not changed much since 1977. Available finish coat technologies were limited to alkyd, acrylic, or urethane based chemistry. Performance of these chemistries has declined over the years due to cost reduction in paint to meet project pricing requirements.

Bridge owners and engineers have had a limited selection of high performance coatings to protect their assets. This is even more important with high profile structures where the finish coat needs to stand the test of time and limited maintenance funding has forced asset owners to extend time in between cosmetic maintenance.

One such project is the Roosevelt Island Bridge. The Roosevelt Island Bridge, owned by the New York City DOT, is a lift bridge spanning the East Channel of the East River. With 170 foot towers and deep cool red color the Roosevelt is easily visible from the Manhattan skyline and required an ultra durable finish coat.
