The Most Recent Test Results of One-Coat Systems Applicable to Steel Bridge Structures

The Most Recent Test Results of One-Coat Systems Applicable to Steel Bridge Structures
Available for download

A two-year Federal Highway Administration (FHWA) in-house study was launched in November 2006 to evaluate various coating materials that may be applied as one-coat systems to steel bridges. A total of eight test materials plus two control systems, a 3-coat and a 2-coat, were applied over near-white steel test panels (SSPC-SP10). Their performance has been evaluated for 20 months using electrochemical impedance spectroscopy, surface failure characterizations, rust creepage at scribe, pull-off adhesion, and changes of color and gloss.

(Coating Formulation) Efficacy of Zinc Content in Sacrificial Protection of Coatings

Product Number: 44-COAT_DEC21
Author: Nicole Rakers / Mary Lyn Lim / Michael McCarthy / James Begley
Publication Date: 2021
$20.00

Zinc rich coatings have long been used in the protective coatings industry as one of the primary means of steel substrate protection against corrosion. The primary protection mechanism has historically been galvanic sacrificial loss of zinc metal and the simultaneous formation of protective zinc oxides and salts. Various standards and customer specifications exist to ensure that the coating will provide the necessary corrosion protection for the life of the asset.

(Coating Formulation) Corrosion Resistance Comparison of Zinc-Rich Epoxy With Reduced Zinc Levels

Product Number: 46-COAT_DEC21
Author: Mary Roley
Publication Date: 2021
$20.00

Zinc-rich coatings have long been known to provide excellent corrosion resistance in highly corrosive environments, in general,inorganic zincs for new construction and organic zincs for maintenance. A recent trend has been toward zinc-rich coatings with reduced levels of zinc dust. An SSPC committee formed to revise SSPC Paint 29, Zinc Dust Sacrificial Primer, Performance Based, to reference performance only, removing reference to minimum zinc dust level.

Early Test Results of One-Coat Systems Applicable to Steel Bridge Structures

Product Number: 41208-427-SG
Author: Seung-Kyoung Lee, Shuang-Ling Chong, Yuan Yao
Publication Date: 2008

A two-year FHWA in-house study was launched in November 2006 to evaluate various coating materials that can be applied as one-coat systems to steel bridges. A total of eight test materials plus a 3-coat system and a 2-coat control system were applied over near-white steel test panels (SSPC-SP10). Their performance is being monitored using electrochemical impedance spectroscopy, various surface failures, rust creepage at scribe, adhesion, and change of color and gloss.
