3M
“No Wax” ESD Tile
One of the key attributes of 3M ESD Vinyl Tile is its ability to be cleaned
and maintained with a minimum of cost and effort.
See 3M ESD Floor Tile 8400 Series instructions for complete
maintenance details.
Unique Cleanability
3M ESD Floor Tile 8400 Series can
be repeatedly cleaned and then
buffed to a high sheen without ever
using wax.
With some other ESD tiles, normal
cleaning procedures may dull the
finish and can even degrade the
electrical properties. Conductive
wax or glaze must then be used to
restore their shine and conductivity.
3M Tiles 8400 Series maintain
their electrical properties and
can be shined like new with
simple buffing. The photos below
demonstrate this feature.
The floor section shown is a test
patch of 3M
8412 installed in a high-traffic area
of a regional telephone company
warehouse. To determine whether
the tile could truly withstand
serious abuse and then be returned
to like-new condition with simple
cleaning and without wax, the
section was intentionally left
unattended for 11 months as it was
subjected to the wear and grime of
continual forklift traffic. The result
of this abuse is evident in Photo 1.
After being swept, the tile was
scrubbed with neutral cleaner, left
to dry, and then buffed according to
the maintenance procedure established. As Photos 2 and 3 show, in
spite of nearly a year of dramatic abuse, the high gloss of the restored
floor finish is similar to that of the tile when it is newly installed—
without the use of any kind of wax.
This trial is an impressive demonstration of the durability of the 3M ESD
tile and its unique “no wax” feature.
