JAP Water Washable Liquid 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.

Instructions for use

Ensure test part is clean and dry, and free from oil, grease and other contaminants.

Apply penetrant by immersion dip, brush, flow on, conventional or electrostatic spray. Cover the test area completely.

Allow penetration time. Minimum penetration time is 2 to 5 minutes, with 10 minutes being adequate for most situations. Lower temperatures thicken the penetrant and require longer penetration times.

Spray the component with clean water at 10°C to 40°C, or wipe with a lint-free cloth dampened with JAC 2 or JAC 3 cleaner. Once clean, the component should be dried before a developer is applied.

Apply a thin layer of developer* to the surface and allow a minimum of 10 minutes development time before inspecting the component under white light. Indications will appear dark red against the white developer background.

* A developer is used to maximise sensitivity and provide a white contrasting background. Two types of developer can be used:

• Solvent-based: quick-drying materials which are applied by spraying. The component under test must be dry before developer is applied.
• Water-based (aqueous): can be applied by dipping or spraying. To maximise penetrant sensitivity, parts should only be exposed to aqueous developers for short periods of time. The component must be dried before inspection.

Developer residue can be removed either by wiping with a cloth or by a water and detergent wash. Penetrant residues can be removed by vapour degreasing or solvent soak.
