Method of Use

Ardrox® 996PB may be applied by aerosol, brushing, flow-on, immersion, spray or by swab.

Pre-Cleaning

Clean part with e.g. Ardrox® 9PR5, 9PR50 or 9PR88 before applying Ardrox® 996PB 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.

Penetrant Application

Surface temperature should be between 10 and 50°C (50-120°F). Apply a thin even film of Ardrox® 996PB penetrant to cover test area. Allow penetrant 10–30 minutes penetration time before removing.

Penetrant Removal

Remove excess surface penetrant with clean cloths, pre-moistened with cleaner (e.g. Ardrox® 9PR5, 9PR50 or 9PR88). 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.

Developer

Shake developer (e.g. Ardrox® NQ1) thoroughly. Spray thin, even developer film over area to be inspected (spraying distance 30 cm / 1 ft.). Allow 10 – 30 minutes developing time before evaluation. Inspection should take place in diffused white light of at least 500 lux at the component surface.

Cleaning

After final inspection, components can be cleaned using e.g. Ardrox® 9PR5, 9PR50 or 9PR88.

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

Effects on Materials

When Ardrox® 996PB is used in the prescribed manner, no significant corrosion is likely to occur on commonly used constructional metals. The product may stain or soften some plastics and rubbers and, where appropriate, a compatibility test should be carried out.
