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.



Fastest inspection processing

  • Reliable, simple 3-step process is a convenient and easy-to-use solution for preventative maintenance and control checks
  • Quickly and completely covers the entire test surface due to high surface wetting
  • Remove excess penetrant without water to eliminate the need to dry parts before applying developer​

Dependable and convenient to use

  • Easy to carry and use in the field with the convenient aerosol cans which are carefully designed for consistent, even coverage and maximum test area coverage
  • Use in all conditions without the need for darkness or UV lights
