For years Network Rail had specified systems with life spans of 20-25 years, such as Acrylic Urethane and Polysiloxane systems but has since begun to specify higher performance coated systems. Representatives at Unova Products describe, “The advent of fluoropolymer top-coated systems has now enabled a significant extension of coating lifetimes to up to 60 years, reduced and a considerable reduction in carbon footprints. In addition, the notable anti-graffiti properties of fluoropolymers also carry great benefits in most locations.”

Created in Japan in the mid-1980s for bridges, Fluoropolymer top-coated paint systems have gained popularity worldwide as a highly sustainable alternative to traditional systems. Unova representatives further explain, “The current global focus on Carbon Net-Zero is arousing much interest in this as it enables a robust reduction in the carbon footprint of projects by extending maintenance and repainting cycles. In addition, fluoropolymers also enhance aesthetics as they provide unrivaled levels of gloss and compared to traditional topcoats.”

The specified coating system for the Shere Heath Bridge was A&I Coatings Vitreflon top-coated N4 paint system. In addition, the system features a topcoat of Vitreflon195 FEVE Fluoropolymer. A&I Coatings’ system is a low-VOC fluoropolymer that features Lumiflon FEVE resin.

Substrates that feature resin are provided with longevity and durability in addition to excellent color and gloss retention, anti-corrosion, graffiti properties, and superior weatherability, essentially protecting architectural from UV radiation, water, salt, and other elemental deterrents that contribute to coating degradation.
