Detect leaks before they become critical! Easily identify leak locations.
We would like to introduce the acid/alkali leak detection paint "OnGuard" handled by CESTEC Corporation. The acid leak detection paint changes from yellow to red when it comes into contact with strong acids with a pH of 3 or lower. After repairing the leak, rinsing the discolored area with tap water or a weak alkaline solution will return it from red to yellow. The alkali leak detection paint changes from white to blue when exposed to strong alkalis with a pH of 10 or higher. After the leak has been repaired, rinsing the leak area with tap water or a weak acidic solution will return it from blue to white. 【Features】 ■ Safety for workers and protection of expensive equipment and the environment ■ Detect leaks before they become critical situations ■ Enhanced safety on site ■ Easy identification of leak areas for anyone *For more details, please download the PDF or feel free to contact us.
