ND CHECK – 732 Solvent Removable Visible Dye Penetrant

It is a solvent removable Penetrant used in a process Of LPI/DPI (Liquid / Dye penetrant inspection for identification and detection of hairline cracks, porosity and discontinuities on the surface of a nonporous material. This is a combination of carefully selected hydrocarbon and diluents with high surface wetting characteristics which allows the liquid to penetrates into the surface breaking discontinuities via capillary action.



Detection of cracks on welds, turbines, reactor vessels, pipes, castings, billets, forging, Aluminum parts, gears, etc.


Apply ND CHECK SPRAY – 731 on the surface which is to be inspected by means of LPI / DPI. Within next 5 – 10 you will have a clean dirt free surface ready for application of ND CHECK SPRAY – 732 (Penetrant). Apply ND CHECK SPRAY  – 732 and allow it to remain on the surface for 15 – 20 min depending upon process so that to enable it to enter in the cracks and crevices.
