Water Washable Fluorescent Penetrant
A Product of Chemetall U.S., Inc.
Ardrox® 970P25E has been approved for sensitivity Level 3.
This penetrant is characterized by its controlled washability, which makes it less susceptible to over-washing. This high entrapment feature truly makes it unique in comparison to other water washable products. Flaw finding is enhanced by its excellent bleed back properties. This product was developed for fracture critical control inspection.
Ardrox® 970P25E has a flash point of well over 300°F (149°C). Very low in odor, it contains no petroleum solvents, no heavy metals, and no fats, oils or greases as constituents. There is no loss of sensitivity due to evaporation nor will this product break down under high temperature conditions. It provides
• Bright, crisp indications
• Low residual background
• Exceptionally high and UV fade resistance
• Over-wash resistance
• Low toxicity

It is recommended that tanks, in the process line, be constructed from stainless steel (Grade 304 or equivalent). For areas which are exposed to water, mild steel may be used provided it is free from rust, scale, and other contaminants.
Ardrox® 970P25E may be applied by aerosol, brushing, tank immersion, conventional, and electrostatic spraying. The following typical process sequence illustrates the recommended method of use.
All surface contamination (rust, paint residues, greases, scale, etc.) must be completely removed. After cleaning, make sure that the component is completely dry and cool, 125° F (53° C) or lower, before applying the penetrant.
2. PENETRANT APPLICATION
Apply penetrant to the surface and leave on for a suitable dwell period. This dwell period is normally 5 minutes minimum. If the contact period exceeds 120 minutes, the penetrant should be reapplied to the surface.
3. WATER WASH – 25 to 40 psi, 1 to 3 minutes, 50° to 100°F (10° to 38°C)
Use either one or a combination of manual spray or automatic spray tank rinses.
The times given are a guide only. Practical trials should be carried out to establish the most suitable conditions for specific components.
4. OVEN DRY, AIR RECIRCULATING
Oven set at 160°F (71°C) maximum.
Use the minimum time necessary to thoroughly dry the components. Use clean, filtered, low-pressure compressed air to remove pockets of water before oven drying.
5. APPLY DEVELOPER
Dry powder developer, Ardrox® 9D4A or D1, may be applied in specially designed dust storm cabinets or by electrostatic spray; dwell time: 2 to 5 minutes. Non-aqueous developers, Ardrox® 9D1B or NQ1, are applied by spray; dwell time: dry, plus 2 minutes. The aqueous developer Ardrox® 9D76 is applied prior to Step 4, oven dry. In most cases developers are required by government or prime contractor specifications.
Component should be inspected under UVA (365-nm) illumination in a darkened area.
EFFECTS ON MATERIAL
Ardrox® 970P25E is non-corrosive to most common metals. It meets the corrosion requirements of AMS 2644 for aluminum, steel, and magnesium. It is compatible with titanium and nickel alloys. It may stain or soften some plastics and rubbers; where appropriate, a compatibility test is recommended.
