Johnson and Allen JAP WW Water Washable Red Dye Penetrant



JAP W/W is a water washable deep red coloured liquid penetrant for use in penetrant testing processes. JAP W/W uses a Hydrocarbon carrier fluid with additives to give a high level of inspection integrity and increase the ‘searching’ properties of the dye. JAP W/W should be applied to clean, grease free components and any surface coatings should be removed prior to inspection.

JAP W/W is ideal for the inspection of welded fabrications, pressure vessels, structures, pipes, castings, forgings, non-porous ceramics and many other non-ferrous and ferromagnetic components.

JAP W/W aerosols use a CO2 propellant which gives an excellent active product to propellant ratio when compared to liquid propellants like Butane, Isobutane and Propane.

Certified to meet Sulphur and Halogen levels required by military, nuclear and ASME standards.

Available in 400mL aerosols and in 5L bulk containers.
