Storage Recommendation
New PVA
Rollers
When these recommended storage procedures are
followed, ITW Rippey guarantees the shelf life of our PVA products to be
one year from the date printed on each bag.
- PVA brushes should be
stored in an ambient temperature environment, (between 65-75 degrees F
or 18-24 degrees C)
- PVA brushes should be
stored in the horizontal orientation so that the fluid the brushes are
saturated with does not migrate to one end
- PVA brushes should not
be stored in direct sunlight
- For best results, store
the PVA brushes in an enclosed container away from any light source
Previously Installed
In order to prevent
bacterial growth, the following recommendations are made for PVA brushes
that have already been installed on a tool. In certain applications,
(especially pilot lines), a scrubber will shut down for an extended period
of time. However, the PVA brush may not necessarily be at the end of its
useful life. In order to be sure the brush performs properly when the tool
is put back into use, ITW Rippey recommends the following procedures:
- Remove the PVA brush and
core assembly from the tool, do not let PVA dry out
- Thoroughly rinse out the
PVA brush with DI water
- Place the PVA brush
only, (or brush and core depending upon customer preference), in a
solution of .15%-.25% NH4OH, (by weight in DI water)
- Keep brushes and solution
in a covered container
- When needed, remove the
brushes and thoroughly rinse in DI water
- The PVA brushes are now
ready to install back onto the tool
