Soluble Salt Opinions?

May 17, 2017
Elzly Technology Corporation is conducting a survey of coating inspectors on the detection and remediation of soluble salts. We invite all coating inspectors to participate in the survey. The survey should take most users 10-15 minutes to complete (dependent on the extent of experience with salt detection and remediation). The survey can be accessed at the following link:

"Over the years, zinc rich coating systems (both organic and inorganic) have been used to mitigate corrosion phenomena. With the increased use of high performance topcoat systems, the focus has again shifted towards mitigating substrate corrosion at defects and hard to coat areas, as these issues are becoming the limiting factor in coating system life. While the protective ability of zinc rich primers is well documented, this testing intends to prove the efficacy of zinc rich primers in protecting complex structures, edges, crevices and weld areas. The testing also addresses concerns about the relative protective ability of coating systems incorporating inorganic zinc rich coatings vs. organic zinc rich coatings as primers. While not universally shared, the plurality of the data seems to suggest that systems with inorganic zinc primers may offer better performance; however the application of topcoats over inorganic zinc has always been a concern. Inorganic zinc primers are also supplied as 2 or 3 component products and require careful mixing and continuous agitation of the supply pot during application to ensure proper distribution of the zinc within the binder. The failure to achieve the proper zinc loading in the film can lead to poor coating performance. This testing evaluated the performance of commercially available zinc primers in conjunction with epoxy and polysiloxane topcoats via laboratory electrochemical testing, modified accelerated cyclic corrosion testing, marine atmospheric exposure testing and mechanical testing. The primers were evaluated over weld beads, complex corners and edges (steel grating) and crevice interfaces where paint tends to break down causing system failure and metal loss. Data results will be shared in the form of coating performance (blistering, rust through, cutback, sacrificial protection against running rust for aesthetic purposes) and sacrificial protection provided by the primer for prevention of metal loss via pit depth and area of attack data.

Title
The Use of Coatings for Corrosion Control on Offshore Oil Structures
Abstract
Protective coatings are ubiquitous on offshore oil structures. As with most situations, the use of coatings is driven by myriad factors unique to the industry. The paper will provide an overview of the types of structures, the coatings used in different zones of the structures, and the pragmatic and regulatory criteria which influence the coating p...

The paper discusses how the US Navy and NSRP Surface Preparation & Coatings Panel are working together to reduce the cost of painting Navy ships. In addition to describing the various entities and how they interact, the paper summarizes several recent initiatives such as the determination of environmental recorder requirements, cost-benefit analysis of salt mitigation, retention of pre-construction primers, humidity control during tank painting, acceptability of flash rust on hydroblasted surfaces, and implementation of single coat tank coatings.

USE OF PRE-CONSTRUCTION PRIMERS IN MARINE CONSTRUCTION
Abstract
Pre-construction primers (also known as shop primers or pre-fabrication primers) are very thin films applied to blast cleaned steel plates and shapes to provide preservation of the blasted steel during the shipbuilding or construction process.

Pre-construction primers (also known as shop primers or pre-fabrication primers) are very thin films applied to blast cleaned steel plates and shapes to provide preservation of the blasted steel during the shipbuilding or construction process. SSPC is developing an industry guide document containing information regarding the use of pre-construction primers (PCP) on structural steel in shipbuilding. This paper will review the technical details contained in the document including background on the reasons to use and retain PCPs, the types of PCPs and their application and inspection, and the secondary surface preparation processes that are used when PCPs are retained in the final, compatible primary coating system.

Title
Zinc Rich Primers for Corrosion Protection
Abstract
Various types of zinc-rich coatings are available for corrosion protection. The challenges associated with the proper specification and application of zinc-rich coatings are briefly discussed. The paper then focuses on data from various studies, which quantify the corrosion protection benefits of various types of zinc-rich coatings.
