How
to ground an esd floor
How
to ground ElectraGuard ESD Epoxy
Reliable grounding of
your ESD flooring is imperative. While copper may start
out being slightly more conductive than aluminum this
conductivity is reduced drastically upon contact with today's
conductive adhesives.
WHY?
Chemical concentrates
used to cure the conductive adhesive rapidly oxidize the copper.
Over a period of several days the copper develops an easy to see
green copper oxide insulative residue. This residue dramatically
reduces
conductivity. Over a period of a year this insulative copper
oxide continues to "grow" in thickness changing the conductivity
of the grounding foil to (in many cases) well over 2,000 ohms. In
addition most copper foil tapes used for grounding esd
floors are a mere .500 wide not providing optimum contact for
long term conductivity.

We take
static control seriously but make compliance easy!®
United SCP's 2" wide High
Purity chemical resistant aluminum foil ground grid tape is the
ultimate mechanism when ground grids are required for your esd
flooring materials. With highly oxidation resistance to
conductive adhesive curing chemicals and excellent long term
conductivity this innovative alloy is far superior to copper.
