High Performance Water Based Coating Enhanced with Nano Vapor Corrosion Inhibitors

High Performance Water Based Coating Enhanced with Nano Vapor Corrosion Inhibitors
Available for download

The use of single component water based coatings for protection of metal substrates continues to grow due to their low odor, health and safety advantages, easy cleanup and environmental friendliness. Nevertheless, the challenge continues to find alternatives to the traditional chromate, zinc or similar heavy metal type corrosion inhibitors which tend to rely on passivation or sacrificial cathodic protection.

The use of single component water based coatings for protection of metal substrates continues to grow due to their low odor, health and safety advantages, easy cleanup and environmental friendliness. Nevertheless, the challenge continues to find alternatives to the traditional chromate, zinc or similar heavy metal type corrosion inhibitors which tend to rely on passivation or sacrificial cathodic protection4. Additionally, ongoing regulatory developments, which require lower VOCs and elimination of carcinogenic materials continue to tighten the usage of products containing these heavy metals thus forcing the need for alternative technologies. The use of nano vapor phase corrosion inhibitors (VCIs) provide an attractive alternative by adsorbing onto the metal substrate and filling the voids or micro-crevices of the substrate and preventing corrosion from starting or growing once the surface of the coating has been damaged. This technology has been proven effective in single component water based coatings at dry film thickness (DFTs) of 1 mil (25 microns).

Corrosion mitigation by the use of barrier coatings relies on polymers and other substances to minimize the permeation of corrosive agents to the substrate. To achieve good barrier properties, most protective coatings rely on high crosslinking density and special fillers to increase the tortuosity of the film. However, this approach usually leads to highly viscous and brittle coatings that take too long to cure. In contrast, flexible and tough coatings typically do not have the requisite barrier properties for enhanced corrosion prevention.

As the author Robert M Pirsig stated, “Technology presumes there’s just one right way to do things, and there never is.” Whilst measuring coating thickness on concrete substrates is not new, the introduction of a new non-destructive thickness (NDT) gauge to measure coatings on concrete not only allows the user to evaluate the results obtained by existing instrumentation, but also provides an alternate non-destructive measuring solution - thereby increasing the industry’s confidence in the overall measurement technology.

This group of authors, thinking outside the proverbial box, and with a mind to Shakespeare’s Macbeth, presented a paper at SSPC 2010 entitled “Hubble, Bubble, Tests and Trouble: The Dark Side of Misreading the Relevance of Coating Testing”. A challenge to the status quo of coatings performance testing, the paper boldly questioned much of the conventional wisdom surrounding coating testing and how that testing is interpreted.
