Ardrox NQ1 Solvent Based Developer 400ml Aerosol

ARDROX NQ1 is a suspension of an inert white powder in a quick drying solvent. It has a low sulphur, halogen and alkali metal content.

ARDROX NQ1 is used e.g. in non-destructive testing of forged parts, welds, casts and drop forged parts. ARDROX NQ1 is used with any of the ARDROX range of visible penetrants.

Method of use:

• Pre-Cleaning Clean part with e.g. ARDROX 9PR88 before applying penetrant (e.g. ARDROX 9VF2 or ARDROX 907PB). Apply wet film of cleaner to part and wipe clean with cloth. Surface has to be free of grease, oil and dirt. Allow part to dry before applying penetrant.
• Penetrant Spray a thin even film of penetrant to cover test area. Allow penetrant 10 - 30 minutes penetration time before removing.
• Penetrant Removal Remove excess surface penetrant with clean cloths, premoistened with cleaner. Alternatively, removal can be done by water spray or by rinsing with water. DO NOT flush surface with cleaner as sensitivity will be impaired. Repeat procedure until surface penetrant has been removed.
• Developer Shake ARDROX NQ1 developer thoroughly until agitator rattles. Spray thin, even developer film over area to be inspected (spraying distance 40 - 60 cm). Allow 10 ° 30 minutes developing time before evaluation.
