Conductive Adhesives: An Integral Part of the ESD Flooring System

Of all ESD flooring products evaluated by architects, engineers and contractors, adhesives receive the least amount of scrutiny. Buyers and specifiers alike agonize over their choice of ESD flooring materials. Yet, despite this lack of attention, adhesives are the critical element in ESD flooring installations, providing structural and electrical integrity – or creating disaster.

Some conductive adhesives require tremendous skill on the part of an installer. Mixing processes along with ensuring that tiles are placed in “wet-set” two-part epoxy adhesives within the proper timeframe require competence and attention to detail. One-part acrylic adhesives must be spread on the floor and subsequently covered with tile with very little margin of error for dry time. After tiles are set, when the floor is rolled, all wet-set adhesives bleed through the seams.

The adhesive and electrical properties of the floor are both integral to making the right ESD flooring choice and should be viewed as a system—not evaluated as singular items.

Many of these factors contribute to heightened labor costs increased to compensate for a slow installation. These and other considerations should be paramount when choosing ESD flooring. But they are not. The fact is, with ESD flooring the adhesive and electrical properties are all integral to making the right ESD flooring choice and should be viewed as a system—not evaluated as singular items.

How Conductive Adhesives Work

Without a conductive ground plane, ESD tiles would have no place to discharge unwanted static charges. Every tile would be like an isolated island – in other words, electrostatic charges would be stuck on individual tiles with no place to go. That would mean anyone walking on the floor would also remain charged.

StaticWorx conductive adhesives don’t just hold the floor in place. The adhesive acts as a conductive ground plane, providing electrical continuity between every ESD tile in a room.

How?

Electricity always flows to the path of least resistance. The electrically conductive fibers suspended in conductive emulsion draw static charges to the adhesive. The adhesive pulls charges downward, away from the surface of the floor, through the thickness of the tiles, to the underlying conductive adhesive/ground plane – the adhesive, in this case, being the fastest path to ground. Charges then move across the adhesive ground plane and transport static safely back to earth, enabling your ESD floor to do its job.

With StaticWorx Adhesives, grounding is straightforward and easy

With conductive adhesives, expensive copper equipotential grounding grids are a thing of the past

Copper equipotential grids, once standard grounding procedure, are no longer necessary.

StaticWorx conductive adhesives link to ground with copper connector strips. The strips can be attached to electrical conduit, building steel or a dedicated grounding bar. Copper ground connectors are 24″ long and are supplied with every StaticWorx flooring shipment. Only one ground connection is necessary for every 1000 square feet of contiguous ESD flooring.

Adhesives and Conductivity

The conductive adhesive must always be more conductive than the surface of the floor.

Why?

Because conductive adhesives form a ground plane under the ESD floor. EC (electrically conductive) adhesives work by drawing charges downward, through the thickness of the tile, across the conductive ground plane, to copper tiles installed at the perimeters of the room, to ground.

The conductive adhesive must always be more conductive than the surface of the floor. 

As we know, electricity always seeks its fastest path to ground. If the flooring material is more conductive than the underlying adhesive, electrostatic (ESD) charges will remain on the floor surface, potentially creating a safety hazard for people walking on the floor.

That’s why all StaticWorx adhesives measure in the conductive range – under 1.0 x 10E6 ohms.

GroundTack Clear Releasable Adhesive

GroundTack is a clear, conductive pressure-sensitive adhesive. GroundTack creates an electrical ground plane, providing total continuity across an ESD flooring installation. Far superior to expensive conductive tapes, messy wet-set black adhesives and complex grounding grids, StaticWorx GroundTack is easy to install and can be walked on immediately. When installed under modular carpet, GroundTack provides an excellent bond while providing the flexibility of a release adhesive. With GroundTack, the adhesive stays tacky and never dries completely; static dissipative carpet tiles are easily lifted and removed for repair, replacement or reuse, without ever even having to put down more adhesive.

For use with ShadowFX ESD carpet tile.

Key Benefits
