Static Control Systems

Static Control (EDS) 5 Stage System – Installation Process

This epoxy system is designed to impart static control properties in the static dissipative range of 1 million – 1 billion (1E6-1E9) ohms resis¬tance when tested with ESD Association test method 7.1.

STEP 1) Surface Preparation
We diamond grind (20-30 grit diamonds) the concrete substrate to a comparable media blasting CSP-3,4. An aggressive surface profile will achieve a better mechanical bond between the substrate and epoxy. We then diamond grind all edges, holes, divots and cracks. This ensures our Industrial grade 2-part epoxy maintains an exceptional bond with the concrete substrate; preventing peeling and chipping.

STEP 2) Surface Repair & Preparation
We vacuum the floor twice to remove concrete dust. We repair and patch any cracks, holes or divots with a fast drying flexible epoxy. We then grind the patches and polish where needed. The floor is vacuumed again twice more to remove concrete dust and any other debris.

STEP 3) Isolation Coat
We measure and mix our Isolation coat of industrial grade 2-part epoxy with 100% solids. We then pour the 2-part epoxy directly onto the substrate and is immediately spread around. It is rolled in a “cross-roll” pattern to insure complete bond to your existing substrate to create a seamless, beautiful finish. This process is time critical and we can do it with care and precision. This is your bond-coat. Our installers and technicians are well trained in assessing and manipulating the epoxy where needed.

STEP 4) Electrical Grounding
We properly prepare grounding points. Metal floor joints, metal equipment bases, and steel columns or posts may be used if they are electri¬cally tested to confirm permanent continuity with an earth ground. We apply a minimum of one grounding point per every 1,000 square feet of flooring. This is sufficient for proper dissipation of static electricity. We apply adhesive-backed copper grounding tape at grounding points. When necessary, we also use copper tape to bridge control joints around columns or different concrete slabs.

Note: Copper tape and the static-dissipative epoxy cannot be expected to maintain integrity over expansion joints that experience wide movement.

Methods of installation include the following techniques:

  1. We use the copper tape to make an electrical connection with the green wire or grounding portion of an electrical outlet. A 4-6 inch portion of the copper tape is adhered to the cured Epoxy Isolation coat. Run the remaining tape up the wall and attach it to the electrical outlet.
  2. We may run a No. 10 or 12 copper wire to any convenient ground bus so that the wire emerges at the floor. At this point, the copper wire and the copper grounding strip are connected (intertwined or soldered). If intertwined, we use a conductive adhesive tape to secure the cop¬per tape with the copper wire. The balance of the grounding strip, typically 4-6 inches is then adhered to the floor.
  3. We use the copper tape to make ground connections with steel columns. The copper tape is adhered to the floor and run up onto the lightly sanded steel column or base. Drill and tap a hole into the steel column or base, and then secure the copper tape using a machine screw and washer.

Note: We may use one, two or all three methods/techniques of installation depending on what is needed for proper grounding.

STEP 5) Application of the Static-Dissipative Epoxy
Once the Isolation coat has cured overnight, we apply the Static-dissipative epoxy top coat of 100% solids epoxy. This top coat provides an extremely durable and safe finish..
