Fluorourethane coatings based on FEVE, fluoroethylene vinyl ether chemistry, have been used globally for over 30 years. This technology has a proven record of outstanding performance against exposure to the elements and has been used in applications ranging from aerospace to architectural structures. Recently, the bridge market has taken notice of this high performance, especially in harsh marine environments. Resistance to degradation by UV light is important to the longevity of a bridge structure, but it could be argued that corrosion resistance is the key performance indicator for a protective topcoat.
Fluorourethane coatings based on FEVE, fluoroethylene vinyl ether chemistry, have been used globally for over 30 years. This technology has a proven record of outstanding performance against exposure to the elements and has been used in applications ranging from aerospace to architectural structures. Recently, the bridge market has taken notice of this high performance, especially in harsh marine environments. Resistance to degradation by UV light is important to the longevity of a bridge structure, but it could be argued that corrosion resistance is the key performance indicator for a protective topcoat. This paper will present the latest performance data on fluorourethane- based coating systems. NTPEP Test No. 3, Cyclic Weathering Resistance (ASTM D5894) and NTPEP Test No. 2, Salt Fog Resistance (ASTM B117) data will be given on the following coating systems: 3coat systems (zinc rich primer/epoxy mid-coat/fluorourethane topcoat) and 2- coat systems (zinc rich primer/fluorourethane topcoat). Comparison of performance between fluorourethane systems and both traditional polyurethane systems as well as polysiloxane systems will also be presented. Xenon Arc and QUV-A accelerated weathering gloss retention will be shown. This data in combination with an exploration of real world case studies of bridge structures using fluorourethane protective topcoats, will illustrate how using fluorourethane protective topcoats can expand the design space. The characteristic high gloss retention exhibited by fluorourethane coatings allows for the use of bright vivid colors that maintain their brilliance for the lifetime of the structure.
Organic modified polysiloxanes are generally recognized as the newest generic class of high-performance protective coating. They have gained commercial acceptance over the last ten years and are now widely used in new construction, heavy duty OEM, marine and industrial maintenance painting. This paper provides an overview of the technology, describes the available types of polysiloxane modified organic coatings and their properties and briefly discusses some recent advances in the field.

Recent advances in the realm of polyaspartic ester finish coat technology have led to significant improvements in their aesthetic and corrosion resistance properties. Of particular interest is an initial comparison of the aesthetic properties of older and new generation polyaspartic ester finishes with both polyurethanes and isocyanate-free polysiloxane finishes.
Silicone alkyds have been utilized by the Navy for over 50 years and remain the only single-component technology that is qualified under MIL-PRF-24635. Although the predominant coating in the Fleet, silicone alkyd coatings continue to provide poor color and gloss retention, poor chemical resistance, low hardness, slow cure times and limited cleanability to running rust.
