Liquid Penetrant is one of the most reliable methods when
seeking to detect discontinuities open to the surface on a
wide array of materials.
We utilize both visible (color-contrast) and fluorescent
dyes as the application dictates. Based upon other factors, the penetrant
may be either solvent removable or water
washable.
When performed in accordance with a properly prepared procedure, liquid
penetrant is capable of detecting very fine
surface discontinuities not visible to the naked eye.
