Study:ESD floor coatings/eSd Epoxy

Overview and goals: The purpose of the following testing is to identify floor coatings that fully comply and exceed the latest recommendations of ANSI EOS ESD S 2020-2007. Current specifications from the Electrostatic Discharge Organization call for esd conductive flooring materials that perform within an electrical resistance range of <1.0E09 as tested per EOS ESD S7.1, yet (list as optional) that personnel that are standing (wearing heel straps) should have an RTG (including person / heel straps and flooring < 3.5E07 (35 meg-ohms). Simply put, conventional industry standards are changing rapidly to better take into account the increased sensitivity of today's advanced micro circuitry. In conflict? Yes! But the writing is on the wall. Conductive flooring that falls in the static dissipative range will soon become obsolete. Chemical coatings that increase the conductivity of existing anti-static (static dissipative) flooring will provide a viable, cost effective alternative to total esd flooring replacement or for use as an economical covering for existing vinyl composition tile (VCT) and bare concrete. Thus it is the goal of this study to provide documented evidence of chemical coating conductivity and to identify materials that may meet the above needs.

Introduction: This report documents a series of electrical conductivity test performed on various substrates including concrete filled metal testing trays rendered esd (static control) compliant via the application of ElectraGlaze ESD Floor Wax, ElectraGuard ESD epoxy Paint and ElectraSeal static control concrete sealer. Grounding of substrate specimen comprised of an appropriately placed Copper 3' x 3' x .125 thick panel reliably attached to primary electrical building ground and placed beneath the concrete filled galvanized substrate testing tray. All materials tested were manufactured in compliance with specifications issued by United ESD Inc to (and by) United ESD approved chemical manufacturers. The following testing was performed in a temperature and humidity controlled environment set to replicate many typical job site environments. All testing was performed in accordance with the Industry Accepted Standards of EOS-ESD S7.1 as specified by ANSI-2020.

Equipment: Equipment interpreting readings of electrical conductivity consisted of a Prostat PRS-801 (S.N. # 4990149) precision resistance instrument operated by a programmed microprocessor (controlling voltage selection, electrification periods and display functions). It should be noted that each reading posted by the Prostat actually consist of over 100 multiple resistivity readings of which the device collects, averages and stores. Collected representative readings from testing procedures were subsequently stored in non-volatile memory storage device and transferred electronically to Notebook Computer. Accuracy of readings at this range (with selected cables and electrodes utilized for this test) is +/- 2%. Original calibration and certification of testing system was performed by said manufacturer on 09/22/07 and is valid for one year from this date. All calibration for testing instruments were provided in accordance with NCSL Z540, traceable through reference standards maintained by the National Institute of Standards and Technology (NIST), by comparison to natural physical constants or self-calibrating ratio type measurements. Data from procedures were collected; results averaged, condensed and documented as follows

E) Bare concrete with topical (2 coats) coating of ElectraGlaze ESD Floor finish

F) ElectraGuard esd epoxy with topical coating (2 coats) of ElectraGlaze ESD Floor finish
