Surface Cleanliness
Surface contamination from salts such as chlorides, sulphates and nitrates have been shown to
lead to blistering of organic coatings, particularly in immersion conditions.
It is not sufficient to measure the cleanliness of the substrate. In a multi-layer coating process,
it is necessary to monitor and record the cleanliness of each layer prior to applying the next
coating. When using amine cured epoxy coatings, for example, in low ambient temperatures or
in high humidity, a surface oiliness or exudate may cause inter-coating adhesion failure.
Elcometer 138 Bresle Kit & Patches
It is essential that the level of contaminants on a surface is measured prior to application to ensure
the quality of the coating and that its optimum lifetime is achieved. If the coating is applied to a
contaminated surface, which is not properly prepared, it could fail prematurely resulting in costly
re-coating and high maintenance costs.
