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

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

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.

This paper discusses the preliminary test results obtained from accelerated laboratory tests and outdoor exposure in a marine environment.

Developments in Testing Standards and Test Equipment for Discontinuities (Porosity) in Coatings

Testing cured coatings for flaws and defects is often a crucial part of the acceptance process for a coating assessed against its specification. This is particularly the case for pipeline and storage tank coatings and for coatings applied for corrosion protection, where discontinuities in the coating can lead to premature failure.

The choice of technologies is influenced by factors such as material cost, labor cost, regulatory conditions, surface preparation requirements, application conditions, time available for work, environmental exposure, warranties and expected lifetime of the coating. Older technologies such as alkyds may still perform adequately in some applications.

This paper will address conditions assessment, test procedures and criteria necessary to make informed decisions on overcoating or not overcoating an aged coating system. It will cover rating of adhesion and film integrity, determination of overcoating risk factors and a selection process for appropriate overcoat systems.
