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 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. It is normally used on welds, forgings, pressure vessels, castings and general metal work, and it lends itself to a production environment where many parts are inspected daily.
SKL-WP2 is listed on the QPL SAE AMS 2644 Qualified Product List.
SKL-SP2 Solvent Removable Visible Dye Penetrant

SKL-SP2 is a solvent removable visible red dye penetrant. SKL-SP2 locates surface-breaking discontinuities with a simple three-step process that is ideal for basic industrial nondestructive testing. SKL-SP2 features high-performance penetrating characteristics and produces clear vivid red indications.
SKL-SP2 is a reliable penetrant testing method for preventative maintenance and quality checks. SKL-SP2 is used to inspect welds, forgings, pressure vessels, castings, general metalwork and can be used in leak testing applications.
SKL-SP2 is listed on QPL-AMS-2644 as Type 2, Methods B, C, and D.
SKL-4C Water Based Visible/Fluorescent (Daul Purpose) Penetrant

Specially designed for chemically sensitive plastic parts, and for leak detection, SKL-4C is a red dye visible penetrant that is water based and water washable. As with most plastic parts, it is recommended that a trial application be used to confirm compatibility.
Indications appear dark purple-red in visible light and fluorescent orange in ultraviolet light. This allows dual range flexibility in the inspection process. SKL-4C can be diluted with water, although it is recommended that a dilution ratio of 1:1 is used for general purposes.
