Electrostatic Behaviour
| Typical Average Resistance to Ground: | Rg ≤ 104 Ω* |
| In Combination with a Sika® Electrostatic Conductive Floor Covering: | Rg ≥ 107 Ω ≤ 109 Ω* |
* Readings may vary, depending on ambient conditions (i.e. temperature, humidity, etc.) and measurement equipment.
Application
Mixing Ratio
Part A : Part B = 83 : 17 (by weight)
Ambient Air Temperature
+10 °C minimum / +30 °C maximum
Relative Air Humidity
75 % maximum
Dew Point
Beware of condensation.
The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate Temperature
+10 °C minimum / +30 °C maximum
Substrate Moisture Content
≤ 4 % percentage by weight
The following test methods can be used: Sika®-Tramex Meter, CM-measurement or Oven-dry-method. No rising moisture according to ASTM (Polyethylene-sheet).
Pot Life
| Temperatures | Time |
| +10 °C | ~120 minutes |
| +20 °C | ~90 minutes |
| +30 °C | ~30 minutes |
Curing Time
Before overcoating Sikafloor®-221 W Conductive allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 26 hours | 7 days |
| +20 °C | 17 hours | 5 days |
| +30 °C | 12 hours | 4 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Applied Product Ready for Use
| Temperature | Foot Traffic |
| +10 °C | ~26 hours |
| +20 °C | ~13 hours |
| +30 °C | ~8 hours |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Consumption
~0,08–0,10 kg/m²
This figure is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level or wastage, etc.

MIXING
Prior to mixing all parts, mix separately Part A (resin) using an electric single paddle mixer (300–400 rpm) or other similar equipment. Mix liquid and all the coloured pigment until a uniform colour / mix has been achieved. Add Part B (hardener) to Part A and mix Part A + B continuously for at least 2 minutes until a uniformly coloured mix has been achieved. To ensure thorough mixing, pour materials into a clean container and mix again for at least 1 minute to achieve a smooth, consistent, homogeneous mix. Excessive mixing must be avoided to minimise air entrainment. During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least once to ensure complete mixing. Mix full units only. Mixing time for A+B = >3 minutes.
APPLICATION
Apply Sikafloor®-221 W Conductive onto the prepared, primed substrate and apply by short pile nylon roller (12 mm), then back roller in two directions at right angles to each other. Ensure a continuous, pore-free coat covers the substrate.
Confirm waiting / overcoating time has been achieved before applying subsequent products.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
