Chloride Test Kits
Surface contamination from salts such as chlorides, sulphates, and nitrates has been shown to lead to blistering of organic coatings, particularly in immersion conditions. To ensure that the chloride has been removed, it is essential that the surface is tested before the coating is applied.
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.
