Virginia utilizes polyaspartic technology to repaint more than 100 steel bridges

Polyaspartic urethane coatings offer cost savings and increased productivity for corrosion protection

Pittsburgh, January 13, 2016 — Two-coat polyaspartic urethane coatings have been used to protect steel bridges from corrosion for well over a decade. A polyaspartic urethane two-coat system features a zinc-rich primer and a high-build polyaspartic urethane topcoat, which replaces the epoxy and polyurethane layers found in a conventional three-coat system. Studies have shown that the application of polyaspartic urethane two-coat systems can save Departments of Transportation up to 20 percent on field repainting costs.

Ahren Olson, market manager, Corrosion Protection, Coatings, Adhesives & Specialties, Covestro LLC and Mark Hudson, project development manager, Bridge & Highway, Sherwin-Williams, will present “Two-coat polyaspartic urethane coatings protect Virginia steel bridge structures for over a decade” at 3 p.m., Tuesday, Jan. 19 during SSPC 2016 in San Antonio. They will discuss the results of a study using two-coat polyaspartic coatings for the field repainting of over 100 steel bridges in Virginia.

The study compares the field performance of polyaspartic urethane two-coat systems and moisture-cure urethane three-coat systems on steel bridges in western Virginia after 10 years of service. The research showed that polyaspartic urethane two-coat coating systems offered corrosion protection equivalent to conventional three-coat systems. With performance being equal, polyaspartic urethane two-coat systems provide significant value to bridge owners with cost reduction in painting operations, accelerated painting schedules and milder traffic congestion. Polyaspartic urethane two-coat systems also exhibit excellent edge protection in areas where corrosion is likely to start.
