Sikafloor® MultiDur ES-39 ECF
Smooth, unicolour conductive epoxy flooring system with high chemical resistance
Sikafloor® MultiDur ES-39 ECF is an electrostatic conductive self-smoothing, coloured epoxy flooring system with high chemical resistance.
- Very good resistance to specific chemicals
- Good crack bridging ability
- Impermeable to liquids
- Electrostatically conductive
System Structure
Usage
The System is used in industrial buildings such as:- Chemical and bunding areas
- Electronic facilities and data centres
Advantages
- Very good resistance to specific chemicals
- Good crack bridging ability
- Impermeable to liquids
- Electrostatically conductive
Colour
Cured system colour | Available in various colour shades. |
Exact colour matching
Note: 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.
Appearance
Smooth, gloss finish

ECF MEASUREMENT CONDITIONS AND SPECIFICATIONS
All measurement values for the system stated in the System Data Sheet (except those referring to proof statements) were measured using the following equipment and ambient conditions:
| Condition or Equipment | Specification |
| Size of ESD-footwear | 42 (EU) (UK: 8; US: 8,5) |
| Test person weight | 90 kg |
| Ambient conditions | +23 °C and 50 % r.h. |
| Measuring device for measuring resistance to ground | Metriso 2000 or 3000 (Warmbier) or comparable |
| Surface resistance probe | Carbon Rubber electrode. Weight: 2,50 kg |
| Rubber pad hardness | Shore A (60 ±10) |
Measurement results during testing
Note: If values are lower or higher than required, additional measurements have to be carried out about 30 cm around the point where the faulty readings are located. If the re-measured values are in accordance with the requirements, the total area is acceptable.

Consumption
Layer | Product | Consumption |
Primer | Sikafloor®-150 Sikafloor®-151 Sikafloor®-156 Sikafloor®-161 | 1-2 × ~0.3–0.5 kg/m² |
Levelling | Sikafloor®-150 Sikafloor®-151 Sikafloor®-156 Sikafloor®-161 | Refer to the individual Product Data Sheet. |
Earthing connection | Sikafloor® Conductive Set | 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®-390 ECF | 2.5 kg/m² |
Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
APPLICATION
ESD CONDUCTIVITY MEASUREMENTS
Recommended number of conductivity measurements is specified in the following table:
| Ready applied area | Number of measurements |
| < 10 m² | 6 |
| ≥ 10 m² and < 100 m² | 10 to 20 |
| ≥ 100 m² and < 1000 m² | 50 |
| ≥ 1000 m² and < 5000 m² | 100 |
If the measurements yield values that are outside of the agreed specification, follow these steps:
- Carry out one additional measurement within a radius of approximately 30 cm around the original measuring point.
If the value of the new measurement meets the agreed specification, the original measurement can be disregarded. If the value of the new measurement does not meet the agreed specification, repeat the measurement described above until the fulfilment of the requirements have been verified. If the requirements cannot be verified, contact Sika Technical Services.
INSTALLATION OF EARTHING POINTS
Refer to Sika Method Statement: Sika Method Statement — Sikafloor® mixing and application
Number of earthing connections per room: Minimum of 2 earthing connections. The optimum number of earthing connections depends on the local conditions and must be specified on drawings or other contract documentation.
