Penetrant Materials
1. Surface energy
2. Specific gravity
3. Viscosity
4. Colour and fluorescence brightness
5. Removability
The colour of the penetrant material is of obvious
importance in a visible dye penetrant inspection, as
the dye must provide good contrast against the
developer or part being inspected.
