Sikafloor® MultiDur ES-31 ECF
Sikafloor® MultiDur ES-31 ECF is a two part, electrostatic conductive self-smoothing, coloured epoxy flooring system with high chemical resistance. "Total solid epoxy composition acc. to the test method Deutsche Bauchemie e.V. (German Association for construction chemicals)".
- Very high chemical resistance
- High mechanical resistance
- Impervious to liquids
- Abrasion resistant
- Electrostatically conductive
Usage
It is used as:- Chemically highly resistant coating for concrete and screed surfaces in bund areas for the protection against water contaminating liquids (contact Sika technical service for specific information)
- Electrostatic conductive wearing layer for areas subject to chemical and mechanical exposure in production and storage facilities
Advantages
- Very high chemical resistance
- High mechanical resistance
- Impervious to liquids
- Abrasion resistant
- Electrostatically conductive
Colour
Almost unlimited choice of colour shades - available on Indent Only.
Due to the nature of carbon fibres providing the conductivity, it is not possible to achieve exact colour matching. With very bright colours (such as yellow and orange), this effect is increased. Under direct sun light there may be some variations and colour variation, this has no influence on the function and performance of the coating.
Appearance
Self-smoothing system – gloss finish

Application
Ambient Air Temperature
+10 °C min. / +30 °C max.
Relative Air Humidity
80 % r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor 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 min. / +30 °C max.
Substrate Moisture Content
≤ 4% pbw using Sikafloor®-150.
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-sheet).
Osmosis caused by rising moisture or incorrect primer application is not covered by the product warranty.
Substrates above 4% but less than 6% pbw maybe primed using Sikafloor®-151,
Please note Sikafloor-151 offers no protection against rising moisture.
Waiting Time / Overcoating
Before applying Sikafloor®-220 W Conductive on Sikafloor®-150/151 allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | 24 hours | 4 days |
| +20 °C | 12 hours | 2 days |
| +30 °C | 8 hours | 1 days |
Before applying Sikafloor®-381 ECF on Sikafloor®-220 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.

| Levelling (if required) | Sikafloor®-150/-151 levelling mortar | Refer to PDS of Sikafloor®-150/151 |
| Earthing connection | Sika® Earthing Kit | 1 earthing point per approx. 200 -300 m², min. 2 per room. |
| Conductive primer | Sikafloor®-220 W Conductive | 1 x 0.08 - 0.10 kg/m² |
| Final conductive coating | Sikafloor®-381 ECF filled with Sika® Aggregate-508* | 2.5 kg/m² Binder + quartz sand |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
*Other quartz sand type will have an effect on the product, such as filling grade, levelling properties and aesthetics. Generally, the lower the temperature the less the filling grade.
