General Description:
Spotcheck SKL-WP2 is a red visible dye, low odor, water washable penetrant. SKL-WP2 exhibits outstanding penetrating characteristics, which provide for increased reliability of discontinuity identification. SKL-WP2’s water wash removability eliminates the need for solvent removers or emulsifiers to remove excess surface penetrant. WARNING: Penetrants attack and even dissolve many kinds of plastic pipe.  Polyvinyl chloride (PVC) pipe is especially vulnerable, and can crumble after only a few days of exposure.  Even diluted penetrant rinsings attack it rapidly.  ABS plastic pipe is nearly as sensitive. When installing plumbing to handle penetrant rinsings, use metal pipe.

Composition:
SKL-WP2 consists of non-volatile penetrating oils, surface active agents (emulsifiers) and dye.

Method of Application: 
Immersion, flooding, brushing, conventional spray, aerosol spray

Penetration/Dwell Time: 
The generally accepted minimum penetration time is 10 minutes. Some specifications may require longer dwell times. SKL-WP2 is generally removed by water spray.
