Ardrox® 9D1B

Ardrox® 9D1B typically used in a penetrant system with Ardrox® penetrants and removers.

Pre-cleaning, penetrant & excess penetrant removal

Clean part with e.g. Ardrox® 9PR5, 9PR50 or 9PR88 before applying the Ardrox® penetrant. Apply cleaner to the part and wipe clean with cloth. Surface has to be free of grease, oil and dirt. Allow part to dry before applying penetrant.

Apply a thin even film of Ardrox® penetrant to cover the test area and allow penetration as per the required time (typically 10-30 minutes).

Remove excess surface penetrant with clean cloths, pre-moistened with cleaner. Removal can also be affected by rinsing with water (over 5°C / 41°F). Do not flush surface with cleaner as sensitivity will be impaired. Repeat procedure until surface penetrant has been removed. Thoroughly dry the component surface before developer application.

Developing

Ardrox® 9D1B are liquid suspensions of solid particles which settle-out on standing; therefore, aerosols and bulk containers must be shaken thoroughly before and during use. Spray thin, even developer film over the area to be inspected (spraying distance 30 cm / 1 ft.). Surface temperature should be between -10 and 50°C (15-120°F). Ardrox® 9D1B must be applied by a light even spray (immersion or brushing will cause a loss of process sensitivity). When Ardrox® 9D1B is used as part of a fluorescent penetrant process, it should be applied by successive spraying until a translucent layer is achieved.

Allow 10 – 30 minutes developing time before evaluation.

Inspection

For color contrast processes, inspection should be carried out in diffused white light of at least 500 lux (approx. 46 ft.cdl) and in the case of a fluorescent penetrant processes under UVA of 365 nm peak wavelength, typical output of 1200 µwatts/cm² at 38 cm from the component.

Note: the procedure above is a recommendation only; where relevant, the process specifications of the approving authorities must be followed.

When Ardrox® 9D1B is  used in the prescribed manner, no significant corrosion is likely to occur on commonly used constructional metals. Ardrox® 9D1B may cause swelling of some rubbers and plastics, the product should be tested for compatibility before application.

Ardrox® 9D1B are available as bulk material and as aerosol.

Store in a cool place, with protection from freezing conditions. Shelf life is 36 Months.
