To achieve the electrical specifications for the static control (esd) flooring materials you have selected your floor must be properly grounded. Proper grounding runs the full gamut from simple to technically challenging. Static control floor grounding techniques are important in even the most basic of environments and critical in protected electronic manufacturing environments, explosive, ordinance and munitions environments. At United Static Control Products we are specialist in grounding your static control floor to a multitude of requirements from basic to advanced.
Although grounding your esd floor is imperative, most installations now dictate a relatively basic grounding method due to recent advancements inherent in the new higher conductivity adhesives. This basic method is now generally adequate in achieving an installed electrical RTG (resistance to ground) close to the center of the flooring systems electrical conductivity range. We generally supply (at no charge with your flooring order) a quantity of grounding hardware appropriate for basic grounding in non-critical standard environments.
The quantity of grounding hardware we provide is for use with installations utilizing one of our conductive adhesive to concrete substrates. All of our ESD flooring materials are designed to work in conjunction with our permanent one part, water based acrylic liquid conductive adhesive (US C 2000), our unique releasable adhesive "Tape" (URAS), or our NEW US C2004 R Liquid conductive releasable adhesive. All adhesives provide reliable anchoring of the flooring, as well as a equiplane of fairly high, permanent conductivity (typical between 1.0E02 and 1.0E04) allowing equalization of electrostatic potential for subsequent elimination via ground straps placed into the adhesive and beneath the esd floors. Your goal when grounding any esd floor is to provide a reliable, long lasting mechanical connection from your ESD flooring and adhesive to a dependable earthed electrical ground in your building and to come as close as possible to the lower middle of the materials specified resistance to electrical ground.
A variety substrates may be covered with esd flooring. Non conductive (insulative) substrates will somewhat affect the conductivity of certain flooring, more so with static dissipative materials like ElectraFloor "Fundamentals"detail
