Soluble Salts Test Kit is used to measure the amount of soble salts deposited on the surface of a substrate prior to paint application. Testing is vital as performance of most coating is dependant on the quality of the surface preparation. Surface preparation should always be clean free from contaminants, salts and oils when preparing a surface for painting. Soluble Salt test becomes a mandatory quality control measure when dealing with environments that are predisposed to high salt spray.
The presence of salts on the substrate can lead to the premature failure of the coating system. Most high performance coating systems require that the substrate be cleaned to a recognized standard before the application of the coating. Once the bresle patch is applied to the surface to be tested distilled water can be analysed using the conductivity meter before being injected into and then extracted from the bresle patch the required amount of times before being analysed again in the conductivity meter. The difference in the two readings show the conductivity of the water, by multiplying the result by 0.4 the presence of salts expressed in parts per million is shown. The BTK-220 Bresle Test Kit includes all the necessary equipment for assessing the level of soluble salts on blastcleaned surfaces prior to coating. Inside the Bresle Test Kit is a conductivity gauge used for the assessment of soluble salt ions as chlorides, sulphates and nitrates. The Bresle Test Kit complies with the ISO 8502-6 and ISO 8502-9 standards, describing the Bresle Method, that state that the conductivity is mainly directly proportional to the concentration of dissolved salts in the solution. Contamination of blast-media The Bresle Kit is also suitable to determine the contamination of blast-media. This prevents the dissolved salts in the recycled abrasive contaminating the surface being cleaned. Features Unique Direct Sampling Procedure (DSP) to ensure high speed and accuracy. Up to 60 times more accurate than other test kits available. Application areas Marine coatings, protective coatings, pipeline coatings.
