Cleaning, restoration and conservation of murals and decorative paintings are three vastly different definitions. Murals get dirty over time. To wash them with a non-invasive cleanser is to “clean” them. You could clean a mural with de-ionized water or mild cleansers. Blowing the dust off with light compressed air, soft bristle brushing or chemical sponging is also considered cleaning. Once we step from a surface dirt removal to a yellowed varnish removal, or penetrated dirt removal, we have entered the conservator’s field.

Extended Connectivity of Zinc Pigments to Provide Enhanced Galvanic Coupling by Partial Replacement with Nanoparticles

Product Number: 51319-13470-SG

Coatings are widely used to mitigate corrosion of highway steel bridges in aggressive exposure environments. Zinc-rich-primer three-coat (ZRP) systems have been used since the 1980’s. However coating failure of ZRP has been identified within 15 years of application well short of typical 75 year bridge design service life. Most of the reported coating failure included corrosion undercutting blistering and delamination. Partial replacement of zinc pigments with nanoparticles in ZRP coating systems have been shown to provide beneficial physical chemical and mechanical properties. These enhanced qualities may provide enhanced performance to mitigate premature coating failure. Earlier research showed that the nanoparticle enriched primer provided comparable corrosion resistance in aggressive environments as conventional three-coat systems. Nonetheless coating performance can be compromised by inappropriate surface preparation before coating application. Exposure to high humidity and surface contaminants (hygroscopic salt) as well as noncompliance to proper anchor profile requirements can initiate coating failure. The purpose of this study was to evaluate the effect of surface preparation with varying surface contaminants on the corrosion performance of a nanoparticle enriched zinc rich epoxy coating (NPE-ZRP) system. Adverse environmental condition exposure to different level of humidity (5% 75% and 100% RH) water immersion and salt contamination were incorporated before the coating application. After adverse exposure NPE-ZRP coating and a traditional ZRP coating (as a reference) were applied over the coupons. Cyclic testing in alternate wet/dry exposure was done for ~5 months. Coating and corrosion behavior was analyzed during the wet exposure of the cyclic testing by Open Circuit Potential (OPC) Linear Polarization Resistance (LPR) and electrochemical impedance spectroscopy (EIS). Physical parameters such as changes in coating thickness pull-off strength and cross-sectional micro-graphic analysis were also assessed to elucidate the extent of coating degradation.

Extending Asset Lifecycle With Inspections And Maintenance

Product Number: 51322-18143-SG

Author: Tim Widing, Cortney Chalifoux

Publication Date: 2022

$20.00

Consistent coating inspections and planned maintenance are essential to asset integrity. Non-existent, delayed, and cursory inspections can allow premature coating breakdown, corrosion, and costly failures. On the other hand, improper maintenance can be ineffective, costly, and wasteful. The challenge involved in executing informative inspections and effective maintenance practices is identifying and understanding the numerous conditions that can contribute to a reduction in the lifecycle of an asset. This paper will discuss some of the aspects involved in identifying coating conditions that are likely to result in failures and developing cost effective coating repair strategies that will extend the life of the asset.

Extending the Function of Concrete as a Cladding Material

Product Number: 41207-299-SG

Author: Lorella Angelini

Publication Date: 2007

$20.00

“Tilt-up" is a state-of-the-art building system in which steel reinforced concrete panels are cast on site and tilted up into their final position. The tilt-up panels are load bearing and also function as cladding elements. With the exceptions of integrally colored concrete, tilt-up concrete panels can look bare and unattractive if a finish is not applied. It is also well known that concrete is not a “perfect” material as it shows porosity and micro-cracks which can lead to deterioration over time.

The hydrocarbon exploration in the ocean and deep sea was started as early as early as the 1850s, when the first drilling was carried out in California, USA. Other early oil explorations activities were later recorded in Pakistan (1886), Peru (1869), India (1890) and Dutch East Indies (1893).1 In 1930s, the development of the Gulf of Mexico as an offshore area started with oil first being produced in 1938.1 The production from the North Sea brought more technical challenges to the offshore industry.
