SKL-WP2
Water Washable Visible Dye Penetrant

Developed for large surface areas and rough surfaces where excess penetrant is difficult to remove with a solvent removable cleaner or emulsifier, SKL-WP2 is a water-removeable dye penetrant for Type 2 penetrant testing in visible white light.

This bright red penetrant is designed to wash off parts with ease, leaving less background for clearer indications – even on rough surfaces. The quick rinsing reduces water usage in the inspection process, and the rinse water is easily treatable for simpler disposal, for a reliable NDT process with less cost per part.
This color-contrast penetrant meets all NDT specifics for dye penetrant testing and can be used on a wide variety of metals, including non-ferrous and ferrous.
​
SKL-WP2 is listed on the QPL SAE AMS 2644 Qualified Product List.
