Ardrox 9PR5
(Alternate name Ardrox HFR)
ARDROX 9PR5 is a water-white, clear, mobile liquid. It is fast drying and has a low sulphur, halogen
and alkali metal content.
ARDROX 9PR5 is a solvent penetrant remover used for the removal of both visible red dye and
fluorescent penetrants. It can also be used as a solvent precleaner prior to the penetrant application for
the removal of oil and greases.
ARDROX 9PR5 is normally used in the nuclear and allied industries where there is a requirement for the
use of non-chlorinated solvent-type penetrant removers.
Method of use :
For precleaning operations, ARDROX 9PR5 is best used by spray or immersion. However, it may be
applied by any other suitable technique, such as brushing or applying via a cloth.
After suitable precleaning, penetrant application and the necessary penetrant contact time, the excess
penetrant is removed with a clean, dry, lint-free cloth or tissue. The next stage is to use ARDROX 9PR5
to remove the final traces of excess penetrant from the surface. This is best done by applying
ARDROX 9PR5 to a cloth or tissue and then wiping over the surface with the cloth. The application of
ARDROX 9PR5 via a cloth should be continued until the cloth picks up virtually no penetrant.
After removal of the excess penetrant, a thin even coat of developer is applied to the components.
