WDP-218-21 Water Leak Detection Paint (Gallon can)
WDP-218 is a water leak detector/color change developer, which when painted on the points of suspected leaks (joints, welds, connections) forms a white powder. On contact with even very small water leaks it undergoes an irreversible blue-green color change at the exact point of the leak. The coating is can easily be removed with a damp cloth.
Apply with paint sprayer, latex paint roller or brush. Keep well mixed while using and do not allow to settle. Avoid contaminating the developer. Coat the developer on welds, joints or any surface where leakage is suspected. Use between temperatures of 35o and 180o F (0o and 82oC).
Colormetric detectors are rapid leak detectors and inexpensive to use. They react chemically with minute leaks causing a visible color change in the developer. WDP-218 color changes from white to blue-green. It can be used to detect water leaks up to 1x10-7 Std cm3/s
WHERE ARE COLORMETRIC LEAK TESTERS USED?
Colormetric developers are used to leak test large single and double walled tanks, pressure and vacuum vessels, laminated, lined or double-walled parts, complex piping systems, flexible containers (such as aircraft fuel tanks), glass-to-metal seals in hybrid packages and systems that inherently contain or will contain water. WDP-218 is used by plumbers, boat builders, construction engineers, vehicle manufacturers, maintenance engineers and anyone else who needs to ensure a watertight seal.
Storage: Keep containers tightly closed in a dry, cool and well-ventilated place. 2 year shelf life. For industrial use only. Keep out of reach of children.
