Formulators of these coatings need to address the legislations strongly pushing toward lower VOC content. All around the World, Governments, Paint Manufacturers and Applicators are still discussing viable options, though there is no doubt that challenges related to higher solids content in coating formulations will continue to increase.
Formulators of these coatings need to address the legislations strongly pushing toward lower VOC content. All around the World, Governments, Paint Manufacturers and Applicators are still discussing viable options, though there is no doubt that challenges related to higher solids content in coating formulations will continue to increase. As developers of a key performance ingredient into these types of coatings, we continue to follow this trend by developing a range of Rheology Modifiers / thickeners with specific products for very high solids and solvent free (100%) protective and marine coatings. For “less” demanding industrial coatings, waterborne systems are seen as trendier but still pushes formulators to consider formulations with high corrosion requirements.
This paper outlines the aggressive service conditions experienced by wellhead casings and the resulting failures seen to date in the Alberta oil patch. Deleterious in-service conditions include; high temperatures and significant temperature fluctuations, expansion and contraction of the steel substrate, and the wet and dry oxidizing micro-environment, the influence of concrete, and a plethora of chlorides and other contaminants elevating the corrosion rate. Previous corrosion mitigation programs and current inspection techniques are reviewed.

Coatings are applied to steel elements exposed in natural waters to mitigate the deleterious effects of naturally occurring physical-, chemical-, and biodegradation processes. Degradation of steel submerged in natural waters can occur due to corrosion and marine fouling. Recent findings indicated that there are synergistic effects of surface fouling to facilitate biocorrosion.
