General Description
Spotcheck SKL-SP1 is a solvent removable (or post emulsifiable) red colour contrast penetrant. SKL-SP1 exhibits outstanding penetrating characteristics which provide for maximum reliability in locating surface-open flaws and discontinuities. 

It can be used over the entire spectrum of industrial applications, where a visible penetrant 
inspection system meets the requirements for surface-open flaw detection. Typical applications include castings, forgings, leak testing, welds and general metal work. SKL-SP1 has also been successfully used on non-porous ceramics and similar materials. However it is not recommended for the inspection of plastic materials, as it may stain, soften or even dissolve the base material under test. 

Composition
SKL-SP1 is composed of a blend of petroleum distillates, plasticiser and an oil soluble  
organic red dye.
