Over the past decade, more than 150 steel bridges in Virginia have been repainted with two-coat polyaspartic urethane coating technology. The results show the polyaspartic urethane two-coat coating systems offer corrosion protection equivalent to conventional three-coat systems.

Two-coat Polyaspartic Urethane Coatings

Two-coat polyaspartic urethane coatings also have the added benefits of providing cost reduction in painting operations, accelerated painting schedules and milder traffic congestion.

This is the topic of a presentation titled “Two-coat polyaspartic urethane coatings protect Virginia steel bridge structures for over a decade” at the NACE Central Area Conference in Austin, Texas, by Ahren Olson, market manager, Corrosion Protection at Covestro LLC. This work was co-authored by Todd Wiliams, lab manager, Covestro LLC, Mark Hudson, project development manager, Bridge & Highway, Sherwin-Williams and C.Wayne Flemings, senior technican for structral coatings, Virginia Department of Transportation.

Polyaspartic Coatings Applications


On Tuesday, August 8 at 8 a.m., Olson will discuss several topics including the advantages and disadvantages of using two-coat polyaspartic coatings for the field repainting of steel bridges and share results from field inspections of Virgina bridges.

Two-coat polyaspartic urethane coatings have been used to protect steel bridges from corrosion for well over a decade and provide excellent edge protection in the areas in which corrosion is most likely to start. Studies have also shown the application of these fast-throughput systems can save Departments of Transportation up to 20 percent on field repainting costs due to productivity advantages.

To M/S Covestro RE : 2 Coats PA COATING Date : 07-08-2017 We are a small Innovative group and interested in two coat POLYASPARTIC COATING. At what price this is available in Mumbai India ? Sounds having very high potential in Indian Market. What kind of surface preparation is required on MILD STEEL substrate ? Sample with detailed literature mentioning actual life in field, Mixing Ratio, Potlife, Suggested thickness of both coats, Salt water resistance and other Anticorrosive properties will be highly appreciated. Thanking you and with high regards Bharat H. Dadia, Director, M.S.Ch.E.(U.S.A,) dadiabharath@gmail.com, 9819491313, 022 25781525, 022 25782892
