0.0 (0)
SikafloorSikafloor®-222 W ESD is a two-component water based epoxy primer with high electrostatic conductivity. It is designed for use in combination with Sikafloor®-200C ESD, and Sikafloor®-260 ESD and Sikafloor®-270 ESD electrostatic conductive coating systems. Sikafloor®-222 W ESD can be used on a variety of substrates, including existing non-conductive coatings or resurfacers and epoxy primed concrete. Sikafloor®-222 W ESD requires a concrete primer prior to application, such as Sikafloor®-160, Sikafloor®-161 or Sikafloor®-1610.

Application
Mixing Ratio
Part A : part B = 18 : 82 (by volume)
Product Temperature
Precondition material for at least 24 hours between +65° to +75°F (+18° to +24°C)
Ambient Air Temperature
+50°F (+10°C) min. / +86°F (+30°C) max.
Relative Air Humidity
80% r.h. max. (during application and curing)
Dew Point
Beware of condensation. The substrate and uncured floor must be at least +5˚F (+3°C) above the dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate Temperature
+50°F (+10°C) min. / +86°F (+30°C) max.
Substrate Moisture Content
Moisture content of concrete substrate must be ≤ 4% by mass (pbw – part by weight) as measured with a Tramex® CME/CMExpert type concrete moisture meter on mechanically prepared surface according to this product data sheet (preparation to CSP-3 to CSP-4 as per ICRI guidelines). Do not apply to concrete substrate with moisture levels > 4% mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter. If moisture content of concrete substrate is > 4% by mass (pbw – part by weight) as measured with Tramex® CME/CMExpert type concrete moisture meter, use Sikafloor®-1610 or Sikafloor®-81 EpoCem.
Pot Life
Material Temperature | Time |
+68°F (+20°C) | ~ 25 minutes |
Sikafloor®-222 W ESD must be applied and distributed immediately after mixing. Do not apply if indicated pot life is exceeded. End of pot life is not visible.
Waiting / Recoat Times
Before applying Sikafloor® ESD coating on Sikafloor®-222 W ESD allow:
Ambient & Substrate Temperature | Minimum | Maximum |
+50°F (+10°C) | 24 hours | 6 days |
+68°F (+20°C) | 12 hours | 3 days |
+86°F (+30°C) | 8 hours | 2 days |
Coverage
4 to 6 mils wet film thickness per coat, at ~ 401 ft2 to ~ 267 ft2 (~ 37 m2 to ~ 25 m2) per gallon (3.78 L)
Product will not cure properly if applied at excessive thickness.
MIXING
Mix full units only
Premix each component separately. Empty Component B into Component A container. Mix both components thoroughly for 3 min using a low-speed drill (300 - 400 rpm) to minimize entrapping air. Use an Exomixer or Jiffy type mixing paddle (recommended models). During the mixing operation scrape down the sides and bottom of the pail with a flat or straight edge trowel at least once to ensure thorough mixing. Upon completion of mixing, Sikafloor®-222 W ESD shall be a uniform color. Do not mix more material than can be applied within the working time limits (i.e. Pot life) at the actual field temperature. Sikafloor®-222 W ESD must be placed and distributed on the application surface immediately after mixing.
APPLICATION
Only start application of Sikafloor®-222 W ESD after the overall priming coat has dried tack-free. Otherwise there is a risk of wrinkling or impairing of the conductive properties. Apply the conductive primer to the prepared substrate which should be pore-free and pinhole-free. If necessary, apply an additional coat of a suitable material to ensure the substrate is pore-free and pinhole-free and provides uniform and complete coverage over the entire substrate.
Electrodes must be installed before the application of Sikafloor®-222 W ESD. The floor should be divided into sections (at expansion joints or doorways when possible) that can be completed without stopping. When ending a section, tape it off to form a clean edge for an adjacent section. The Sikafloor®-222 W ESD must be applied with a 3/8” nap roller and roller trays. 18 inch (46 cm) roller assemblies and trays are preferred. The roller should be wet in the tray and then the excess coating is removed by lightly rolling in the tray so as to avoid drips.
Then apply 3 pairs of 6 - 8 foot (approx. 1.80 m - 2.40 m) long paths on to the floor. Then spread the material with roller passes perpendicular to the paths of coating. It is extremely important to apply the coating at a rate of 4 - 6 mils (100 - 150 µm) to achieve proper appearance, texture, and color development, and consistent ESD properties. If areas are too thick, the coating may be too soft, if too thin, the coating will appear very flat in sheen and may exhibit poor electrical properties. Work evenly to avoid late “tie-in” and re-rolling to adjacent previously applied material; Doing so may result in color variations.
When Sikafloor®-222 W ESD is used in conjunction with Sikafloor®-200C ESD/Sikafloor®-250 ESD, or -270 ESD, test the primed surface for conductivity prior to the application of Sikafloor®-200C ESD/ Sikafloor®-700C ESD. A value of < 10 X 103 ohms per ANSI/ESD S7.1/ASTM F-150 must be achieved.
Caution: Excessive application thickness will result in “skinning over” which will result in soft, uncured product on the floor and unacceptable conductivity readings. Do not exceed recommended application thickness. Beware of pockets, “bug holes” or other depressions in the concrete surface where Sikafloor®-222 W ESD may accumulate during application. Examine cured Sikafloor®-222 W ESD surface for non-uniform appearance which may
indicate areas where the product was applied in excessive thickness. These must be removed, prepared again and recoated prior to application of the top coat. Properly applied Sikafloor®-222 W ESD will exhibit a uniform dull black finish.
CLEANING OF TOOLS
Sweep up spill and place in closed container. Dispose of in accordance with applicable local, state and federal environmental regulations. Uncured materials can be removed with approved solvents.
CLEANING
Avoid direct contact with eyes and skin. Wearing chemical resistant goggles/gloves/clothing, collect spill. Ventilate area. In absence of adequate ventilation, use properly fitted NIOSH respirator. Sweep up spill and place in closed container. Dispose of in accordance with applicable local, state and federal environmental regulations. Uncured materials can be removed with approved solvents.
