Product Description
CDP-100-15 Chlorine Color Change Leak Detecting Paint (12 oz. Aerosol)
Color changes from White to Yellow when paint is exposed to chlorine. Easy to clean off.
Colormetric detectors are rapid leak detectors and inexpensive to use. They react chemically with minute leaks causing a visible color change in the developer. They can be used to detect leaks up to 1x10-7 Std cm3/s CDP-100 dries fast and produces a consistently even coat. It is suited for use outdoors and in well ventilated areas.
WHERE IS CDP-100 USED?
Testing of large single or double-walled tanks, pressure and laminated, lined or double-walled pipes, complex piping systems, flexible containers and systems that inherently contain or will contain chlorine. Ideal for testing single or double-bottomed tanks or when used to test containers where leaks are critical such as those that contain chlorine. It can detect leaks in piping, valves, fittings and containers with welded, fitted or laminated sections that can be sealed at their ends or between their outer and inner walls.
METHOD DESCRIPTION
A white coating of CDP-100 is sprayed or painted onto welds, joints, fittings or any other area of a vessel containing chlorine which may be susceptible to leakage. The coating clearly changes color from white to yellow with as little as 10 ppm chlorine. This method consists of testing a container already filled with chlorine or by introducing chlorine (or a chlorine-air mixture) into a container or system so that the final chlorine percentage is between 1% and 100%. The chlorine flows through leaks and reacts with CDP-100 that is applied on the other side producing a visible color change. CDP-100 is easily removed with a damp cloth.
APPLICATION
CDP-100 can be applied as an aerosol or with conventional paint brushes (when purchased in the gallon packaging) or air sprayers. It should be allowed to dry and given enough dwell time for the tracer to penetrate. The color change will take place at the point of leakage. The coating is removed easily by wiping with a damp cloth.
BENEFITS
• The method can be used to locate and measure the size of leaks either as a quality control test or as a field-inspection procedure.
• It is quick and inexpensive, making it the best solution for testing large or complex systems.
• It is very sensitive so that it can be used in the most demanding applications.
• It requires a minimum of pressure differential, making it ideal for many difficult applications.
• The sensitivity is completely controllable making it easy to use for different applications.
• It is easy to take photos of the test results, making work easy to substantiate.
Coverage: One aerosol can covers about 20 -25 sq ft.
INTERFERENCES
This method is best for smaller leaks, very large leaks should be tested first using gross detectors such as an Ultrasonic Leak Detector. Interferences include hydrogen chloride, hydrogen fluoride, hydrogen bromide, hydrogen iodide, fluorine and bromine vapors.
