Moving beyond the 25-year coating for steel bridges

Longer-lasting coatings systems focus of Covestro presentation at SSPC 2018

Pittsburgh, January 15, 2018 — Over the past 40 years, three-coat systems featuring zinc, epoxy and polyurethane have been the preferred coating system for steel bridges in corrosive environments. Field studies have shown this system to last more than 25 years with proper application and inspection during installation. Now, asset owners within the industrial maintenance market want to move to even longer- lasting coating systems.

This will be the focus of a presentation by Todd Williams, lab manager for protective coatings at Covestro LLC and Paul Vinik, cathodic protection manager, Greenman-Pedersen, Inc., at SSPC 2018. This event is presented by the Society for Protective Coatings (SSPC).

On Wednesday, Jan. 17 at 11 a.m., Williams and Vinik will present “Moving Beyond the 25 Year Coating.” They will discuss the results of a study examining two important variables within the traditional three-coat systems for steel bridges in corrosive environments:

  • Zinc rich primer type – organic or inorganic – and its impact on accelerated and natural corrosion
  • Topcoat selection – polyurethane, polysiloxane, moisture cure urethane, and fluorourethane – and their impact on corrosion resistance and weatherability


Their presentation will also feature recommendations for moving beyond the 25-year coating on bridges.

Covestro is a gold sponsor of SSPC 2018, taking place in New Orleans, Jan. 15-18.
