Drawbacks of Corrosion Creep as a Performance Indicator for Corrosion Protective Coatings

Product Number: 51323-19270-SG

Author: Andreas Løken, Anders W. B. Skilbred

Publication Date: 2023

$20.00

One of the most common ways of protecting steel assets and structures is by organic protective coating systems. The performance of such protective coating systems is assessed based on results after accelerated laboratory exposure testing, where one attempts to mimic the conditions the coatings will be exposed to under in-service conditions in a significantly shorter time frame. Such testing is also how coating systems are qualified for certain corrosivity classes and durabilities, being formalized in standards and specifications such as ISO 12944-6 and NORSOK M-501 ed. 7.

EIS Evaluation of Single Layer Coating Performance in Corrosive Environments

Product Number: 51220-257-SG

Author: Donald C. Lawson III

Publication Date: 2020

$20.00

Substrate preparation which includes the removal of contaminates, abrading or etching to create a surface profile via mechanical or chemical methods have a major impact on the adhesion performance of applied coatings. For coatings, a primary performance characteristic is adhesion after exposure to corrosive environments. One of the consequences of corrosion forming under a coating is the loss of adhesion or delamination of the coating.

EIS Study on the Behavior of High Performance Topcoats Over Metal Substrates

Product Number: 51219-201-SG

Author: Donald C. Lawson III

Publication Date: 2019

$20.00

Electrochemical impedance spectroscopy (EIS) is used to evaluate the influence of a topcoat to impact corrosion protection after accelerated exposure testing (QUV, xenon arc, Prohesion). The ability to monitor early undercoat corrosion, at progressive stages of the accelerated weathering tests, was a major factor in selecting the EIS testing method.
