Test Method Development for Improved Laboratory Accelerated Weathering of High Performance Coatings

Test Method Development for Improved Laboratory Accelerated Weathering of High Performance Coatings
Available for download

The use of accelerated laboratory artificial weathering in coatings development is necessitated by the lengthy times required for natural outdoor weathering. Across a broad range of industries, weathering results from materials exposed in subtropical South Florida have become the benchmark to which accelerated test methods are compared.

The use of accelerated laboratory artificial weathering in coatings development is necessitated by the lengthy times required for natural outdoor weathering. Across a broad range of industries, weathering results from materials exposed in subtropical South Florida have become the benchmark to which accelerated test methods are compared. To date, there is substantial inconsistency in correlations between the Florida and laboratory accelerated exposures. An industry consortium of coating OEMs, material suppliers, users and test houses has collaborated on developing a new accelerated test protocol that has demonstrated greatly improved correlation. This new method focuses on both an improved spectral match to sunlight as well as a major improvement to moisture delivery. The new protocol is detailed as well as the validation of the method for high performance automotive and aerospace coatings. This improved method overcomes many of the known shortcomings of industry standard methods and may have major implications for the testing of other systems such as high performance exterior architectural coatings. More importantly, it serves as an example and overall framework for development improved test methods.

Study of Scribe Type on Accelerated Underfilm Corrosion Creep

Product Number: 41211-642-SG
Author: Carl W. Reed
Publication Date: 2011
$20.00

The creepage of corrosion underneath a coatings film applied to a steel test panel is often used as a performance test for the anti-corrosion properties of a coating system. Creepage is defined as the degree of corrosion (usually measured in mm) emanating away from a scribe line underneath a coating film applied to a steel substrate. There are several factors which may affect the degree of corrosion creep, one of which is the type and width of scribe cut into the coatings film to the steel substrate. There is a variety of scribing methods used in various test methods and specifications; however it is unclear if there is actually a performance difference observed in corrosion creep when using different scribe types.

New Developments in Surface Profile Measurement for Blast Cleaned Surfaces

Product Number: 41213-746-SG
Author: J F Fletcher
Publication Date: 2013
$20.00

When protective coatings are to be applied to structures, it is important that the surface is clean and dry if premature failure of the coating is to be prevented and the full coating service life achieved. In many situations for both new build and repair of structures, blast cleaning of the surface is required to remove contamination and to create an anchor pattern to enhance the adhesion of the coating system to the substrate.
