Hychem 177ESD HD — Dissipative antistatic epoxy floor system, 2 mm self-levelling, for vehicular traffic

Four layers, slab to surface:

• Concrete substrate
• Primer SD, dissipative plane — Hychem GP Epoxy Primer
• 177ESD TC seal coat — 177ESD SL, dissipative topping

Earth points are installed once the primer has cured, before the dissipative plane goes down.

Each layer earns its place. The GP Primer seals the slab; Primer SD lays a continuous black dissipative plane connected to the earth points; and the 177ESD SL topping carries charge from the surface down through its carbon nanotube network to that plane. Because the conductive path is in the material itself, the copper tape and gridding a conventional ESD floor depends on is largely eliminated, and with it the most common cause of failed conductivity readings.

A thin film option is available where a light traffic area needs static control without the topping build. The TC coating system of GP Primer, Primer SD and two coats of 177ESD TC meets the same resistance targets and is suited to cleanrooms, laboratories and light traffic equipment rooms. It is not included in this standard nomination unless separately specified. 6 m²/L · aluminium oxide grit as required Black conductive layer · 8 m²/L · connected to earth points Seals and keys the substrate · 6 m²/L Ground or shot blasted to CSP 2 · 25 MPa min, 1.5 MPa surface tensile 2 mm Self-levelling epoxy · 2 mm · 2 L/m² · nanotube conductive network Approximately 2.2 mm above the primer: 2 mm

Do not substitute the build-up. Conductivity is a system property. Consumption rates, layer sequence and earthing layout are set together to achieve the specified resistance to earth. Substituting a layer, a product or a rate compromises the specified performance of the system. 2 mm · 2 L/m²

Concrete must be a minimum 25 MPa compressive strength with 1.5 MPa surface tensile strength, cured a minimum of 28 days, firm, clean and dry. Prepare by grinding or shot blasting to the appropriate CSP in accordance with NACE 02203 or ICRI Technical Guideline No. 03732. Do not apply over damp surfaces or where rising moisture is present.

Apply between 10 and 30 °C with the substrate at least 3 °C above dew point. Observe 21 °C at less than 85 % RH, or 10 °C at less than 75 % RH, to avoid amine bloom. Primer SD applies between 15 and 25 °C at less than 80 % RH, a narrower window than the other layers, so plan pours accordingly.

Substrate and air temperature, humidity, dew point, batch numbers and consumption rates are to be recorded through application and cure. These records, together with the between-coat and final conductivity results, form part of the completed project documentation.

• Hychem GP Epoxy Primer — A general purpose, solvent free epoxy primer that seals the prepared slab and anchors the system. Applied at 6 m²/L. Also used as an epoxy mortar for patching, re-levelling and forming falls where required. Earth points are installed once it has cured, before the dissipative plane goes down. VOC content 14 g/L.
• Hychem Primer SD — A two component, solvent free black dissipative layer, the conductive plane beneath every Hychem dissipative coating. No odour, with excellent adhesion to concrete and masonry, and recommended for cleanrooms, electronics production, hospitals and pharmaceutical facilities. Applied at 8 m²/L and overcoated within 24 hours.
• Hychem — 177ESD SL network. Hard wearing and impervious, resistant to fuels, lubricants, most solvents and many chemicals, and rated for vehicular traffic. Textured finishes available to meet slip resistance requirements.
• Hychem 177ESD TC — The coloured, gloss dissipative epoxy coating that seals the system, applied at 6 m²/L with aluminium oxide grit broadcast as required for slip resistance. Also specified alone over Primer SD as a thin film system for light traffic areas.

Seamless self-smoothing gloss, with slip resistance fully customisable through the aluminium oxide grit broadcast into the TC coat, set zone by zone to whatever rating the area demands and rated to AS/NZS 4586. Slip resistance testing of the actual finish can be arranged on request.

Light Grey N35 is the standard colour and is available for any size of area. The full range at hychemcolours.com.au is available subject to colour minimum order quantity. Conductive materials can subtly affect the finished colour, most evident in lighter shades, so confirm with a sample panel before the colour is locked in.

Beyond protecting sensitive electronics, the dissipative surface prevents electrostatic charge accumulating in areas subject to fire and explosion risk, including solvent stores, munitions and hazardous goods handling.

Earth point locations are to be nominated by the electrical engineer or the builder and marked up on the floor plan before coating works begin. Once the topping is down the position is fixed, and adding a point later means cutting into a finished floor.

Flooring applicator: Installs the earth point hardware within the floor build-up: the fixing into the slab, the copper tape connection, the stainless steel grounding plate and the terminal. This is done once the GP Primer has cured and before the Primer SD dissipative plane is applied, so the point is encapsulated by the system. Also responsible for protecting the terminal through the remaining coats, and for cleaning it down once the system has cured.

Electrical engineer or licensed electrical contractor:

• Nominates the number and position of earth points for each area, in line with the minimums above and any project or client ESD control programme requirements.
• Connects each earth point terminal back to the building's electrical earth once the floor is fully cured.
• Confirms continuity of that connection and compliance with AS/NZS 3000 and relevant site electrical requirements.
• Certifies the earthing installation.
• The floor cannot dissipate charge until the final connection is made. Connection to building earth is a hold point at the end of the works, not something to be picked up after handover. Confirm the electrical contractor has this in their scope and programme before the floor is poured.

Once the topping is down the position is fixed, and adding a point later means cutting into a finished floor. Quantity One earth point per 100 m² is the maximum permitted spacing. Hychem recommends one point per 50 m² as best practice, particularly in larger open areas and where the floor will carry heavier or wheeled traffic. Per slab Each slab requires its own earth point, joint to joint, regardless of area. A 50 m² slab still takes one point. The dissipative plane does not carry across a joint, so each side of a joint needs its own connection. Redundancy In high traffic areas, allow a spare point in case the first is damaged over the life of the floor. The cost at installation is negligible against retrofitting one later. Position Point centres sit between 40 mm and 100 mm from the wall, with 100 mm being the typical Hychem position. Locate them out of the way, where they will not be built over by fixed plant, racking or partitions, and where the connection stays accessible for future testing. Marking up Positions are to be marked on the floor plan by the electrical engineer or builder and confirmed on site before the GP Primer goes down. The setout is to be issued to the applicator ahead of the works so the points can be installed at the correct stage. No grid required A conventional ESD floor relies on a copper tape grid bonded to the primed slab, typically run out at around 5 m by 5 m centres, to carry charge back to the earth points. The 177ESD SL topping carries the conductive network within the material itself, so copper tape is used only at the earth point, to bond the dissipative plane to the grounding plate. Flooring applicator Installs the earth point hardware within the floor build-up: the fixing into the slab, the copper tape connection, the stainless steel grounding plate and the terminal. This is done once the GP Primer has cured and before the Primer SD dissipative plane is applied, so the point is encapsulated by the system. Also responsible for protecting the terminal through the remaining coats, and for cleaning it down once the system has cured. Electrical engineer or licensed electrical contractor Nominates the number and position of earth points for each area, in line with the minimums above and any project or client ESD control programme requirements. Connects each earth point terminal back to the building's electrical earth once the floor is fully cured. Confirms continuity of that connection and compliance with AS/NZS 3000 and relevant site electrical requirements. Certifies the earthing installation. The floor cannot dissipate charge until the final connection is made. Connection to building earth is a hold point at the end of the works, not something to be picked up after handover. Confirm the electrical contractor has this in their scope and programme before the floor is poured.
