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
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.
Bridge coatings have evolved significantly over the years, which has led to wide array of coating types for the bridge coatings community to choose from. This paper will briefly discuss the evolution of bridge coatings through time and will also discuss the most current systems deployed in the coating of structural steel bridges. The primary focus of this paper will be centered on one of the newer technologies available, polysiloxane.

A new patent-pending resin technology incorporated into the epoxy/polysiloxane part A portion of a two-component coating system, using an amino-silane curing agent, has shown significant improvements in flexibility, gloss and color retention. Corrosion resistance and adhesion to non-sandblasted metal substrates have also shown improvements. The new resin technology may be considered for low-VOC and HAPs coating systems.
