What is Chemetall S72 Solvent Remover?
Chemetall S72 Penetrant Remover is a volatile solvent which is used for the removal of surface excess penetrant in the solvent removal process or ‘wipe-off’ technique. It is also ideal for the pre-cleaning of surfaces before the penetrant is applied for the removal of oil, grease and other organic contamination.
Method of use
- As a pre-cleaning solvent
Chemetall S72, S76 or S85 should be sprayed directly onto the contamination to be removed. The surface may then require wiping or flushing with the solvent cleaner depending upon the level of contamination to be removed. For best results, the surface should be given a final wipe over with a clean cloth or tissue dampened with S72, S76 or S85.
- For the removal of excess penetrant
When S72, S76 or S85 is used to remove excess penetrant at the end of the penetrant contact time, it is applied to the tested surface using the wipe-off technique. The bulk of the surface excess penetrant is wiped away by using clean, dry absorbent cloth or paper; then Chemetall S72, S76 or S85 is applied to a similar cloth or paper and the tested surface is wiped again until a satisfactory level of background is achieved. Surface temperature should be between -10 and 50°C (15-120°F). Never apply solvent penetrant removers by direct spray on or immersion of the tested surface for the removal of the excess penetrant as this will lead to a loss in sensitivity of the process. LD7 or LD9 non-aqueous developer can then be applied to the dry surface. For Checkmor® 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 Britemor® fluorescent penetrant

- Effects on materials
When S72, S76 or S85 is used in the prescribed manner, no significant corrosion is likely to occur on commonly used constructional metals. S72, S76 and S85 may cause swelling of some rubbers and plastics. If S72, S76 or S85 is to be used on synthetic surfaces, inc. (source)
