Selecting the Right Epoxy ESD / Conductive Flooring

June 15, 2015

Conductive and Electrostatic Dissipative (ESD) flooring are used on floors in facilities that need protection for stray static discharges. One example of static discharge is when you walk across a carpet in a very dry room in winter then touch a metal object or another person you get that little electrical zap. Most people find this a bit of nuisance. However if you touch a hard drive or a circuit board and create that same discharge you can damage it beyond repair. Worse yet if you get a static discharge in a chemical or munitions plant where there might be a potentially explosive environment the results can be a catastrophic explosion.

What is ESD Versus Conductive?

Conductive floors have between 100,000 and 1,000,000 ohms of resistance. Electrostatic Dissipative (ESD) floors have between 1 million and 1 billion ohms of resistance. Remember Ohms Law:

Ohms_Law

where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm’s law states that the R in this relation is constant, independent of the current.

Simply speaking the resistance is the ohms of resistance that we are talking about above. The lower the ohms of resistance the stronger the conductive medium to conduct the static charge away. The lower the ohm of resistance the more efficiently the conductive/ESD flooring carries the static charge safely away. .This is one situation where the smaller the number the better.

How does Conductive and Electrostatic Dissipative (ESD) flooring Work?

Think of your Conductive and Electrostatic Dissipative (ESD) flooring as a grounding rod. A grounding rod is that metal rod that gets driven into the earth to increase the surface area coming in contact with the ground. You then attach your building ground or lightening rod to that grounding rod. The Conductive and Electrostatic Dissipative (ESD) flooring is much like that. It makes the whole concrete surface that the Conductive and Electrostatic Dissipative (ESD) flooring comes in contact with a large grounding plane, acting much like a grounding rod. In some facilities this effect is enhanced even more with the installation of grounding strips that the Conductive and Electrostatic Dissipative (ESD) flooring connects to the grounding rod(s). .

Where do you use Conductive and Electrostatic Dissipative (ESD) flooring?

Typically ESD flooring is used in areas to protect electronics. Conductive is more commonly used where there is the potential for an explosive environment. Most facilities that require ESD flooring can use conductive flooring as well. The reverse is typically not true. Facilities that require Conductive Flooring typically cannot use ESD flooring. The good news is that most Epoxy.com ESD flooring can be made to be conductive by first priming with Epoxy.com Product #671 Conductive Primer Sealer – www.epoxy.com/671.aspx.
