Chloride contamination in the blasting process – an underestimated risk
Especially in industrial environments, abrasive media or water can be contaminated with chlorides – particularly when materials are recycled. These impurities promote corrosion and lead to premature coating failure.
Why monitor chloride levels?
Chlorides, especially from contaminated abrasive or reused water, remain on the surface and can cause corrosion under the coating – often without being immediately visible.
Elcometer measurement solutions at a glance
- Elcometer 134A Test Kit – measures chloride levels in abrasive media using a simple titration with a color change indicator. The value is read in ppm. (elcometer.com)
- Elcometer 134W Test Kit – specifically for measuring chloride ions in water, e.g., during high-pressure water jetting. (elcometer.com)
Practical tip for use
Use these kits regularly when reusing media • measure chloride content directly before coating application • and document the values for quality management records.
Advantages at a glance
- Prevents premature coating failure
- Enables targeted post-treatment or replacement of contaminated media
- Improves quality assurance and cost efficiency
