A Review of Optically Active Coatings

A Review of Optically Active Coatings
Available for download

This paper proposes to identify the differences in chemistry between the two types of OAA and the potential shortfalls in the use of each type under practical working conditions. It will also highlight the proven benefits of these additives in service.

Over a number of years, the use of Optically Active Additives, either organic or inorganic, has increased greatly. Their use is specified by a number of fleets, both naval and commercial, around the World and their use is now expanding into concrete substrates as found in wastewater treatment plants, bridges, roadways and infrastructure. There is now an SSPC Technology Up-date (Ref 1) for the technique. There is a body of evidence that shows there can be limitations in their use under certain circumstances. These can include false positives, cost, migration, and system limitations. This paper proposes to identify the differences in chemistry between the two types of OAA and the potential shortfalls in the use of each type under practical working conditions.

A Study of the Effect of Film Thickness and Blast Profile on Accelerated Underfilm Corrosion Creep

Product Number: 41213-779-SG
Author: Carl W. Reed
Publication Date: 2013
$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. Underfilm corrosion creep, also sometimes referred as scribe creep in the laboratory environment, is defined as the degree of corrosion emanating away from a scribe line underneath a coating film applied to a steel substrate.

A New Protocol for Evaluating the Effectiveness of Coatings Used to Reduce Corrosion of Steel Structures

Product Number: 51220-295-SG

Details of a new protocol for evaluating the effectiveness of coatings to reduce corrosion of steel structures is presented in this paper. Basic concepts of accelerated testing specified in American Society for Testing Materials (ASTM) standards and recent research investigations were used to develop a procedure that can provide conclusive results within 2400 hours of exposure as compared to more than 5000 hours in current practices.

A Viable Alternative to Mineral Abrasive

Mineral abrasives such as glass bead and aluminum oxide have been traditionally used in the surface finishing industry. The general perception is that they offer acceptable cleaning at a low operating cost. Often dismissed is the potential of metallic alternatives that though seemingly higher in initial procurement cost, offer several differentiating advantages in terms of recyclability, consistency of finish, repeatable results and ultimately resulting in overall, reduced operating costs.
