Chemical resistance
Sikafloor®-2350 ESD provides the chemical resistance. Refer to Product Data Sheet.
Electrostatic behaviour
| Resistance to ground | RG < 109 Ω |
| Typical average resistance to ground | RG < 105–106 Ω |
| Body voltage generation | < 100 V |
| System resistance | RG < 109 Ω |
Note: Measurement results can be affected by ESD clothing, ambient conditions, measurement equipment, cleanliness of the floor and the test personnel.
IMPORTANT
ESD footwear requirements
The ESD shoes used in the EPA must have a resistance of < 5 MOhm according to IEC 61340-4-3 at climate class 1 (12 % relative humidity / +23 °C). In order to achieve charges of < 30 volts of human body charge during the walking test (at 12 % relative humidity / +23 °C), we recommend using the following ESD shoes: Weeger ESD clog, art. 48512-30, www.schuh-weeger.de.
Service temperature
| Short-term, maximum 12 hours | +60 °C |
IMPORTANT
No simultaneous mechanical and chemical strain
While the product is exposed to temperatures up to +60 °C, do not also subject it to either chemical or mechanical strain, as it may cause damage to the product.
Application
Ambient air temperature
Maximum | +30 °C |
Minimum | +15 °C |
Relative air humidity
Maximum | 80 % |
Dew point
Refer to the individual Product Data Sheet.
Substrate temperature
Minimum | +15 °C |
Maximum | +30 °C |
Substrate moisture content
Refer to the individual Product Data Sheet.
Waiting time to overcoating
For the waiting time to overcoating of the primer, refer to the individual Product Data Sheet.
Before applying Sikafloor®-2350 ESD on Sikafloor®-220 W Conductive, allow:
| Temperature | Minimum | Maximum |
| +15 °C | 26 hours | 7 days |
| +20 °C | 17 hours | 5 days |
| +30 °C | 12 hours | 4 days |
Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.
Applied product ready for use
Temperature | Foot traffic | Light traffic | Full cure |
+15 °C | ~48 hours | ~3 days | ~7 days |
+20 °C | ~24 hours | ~48 hours | ~4 days |
+30 °C | ~16 hours | ~36 hours | ~3 days |
Note: Times apply when the last layer of the system has been applied. Times are affected by changing ambient conditions, particularly temperature and relative humidity.
Consumption
| Layer | Product | Consumption |
| Primer or scratch coat | Sikafloor®-151 Sikafloor®-161 | ~0.3–0.5 kg/m² |
| Earthing connection | Sikafloor® Conductive Set | 1 earthing point per ~200 m² to 300 m². Min 2 per room |
| Conductive primer | Sikafloor®-220 W Conductive | 1 × 0.08–0.10 kg/m² |
| Conductive wearing layer | Sikafloor®-2350 ESD + Sika® Extender T | ~0.8–1.0 kg/m² + 1.5–2 % (by weight) |
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
Refer to Sika Method Statement.

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, you may 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: Mixing & Application of Flooring Systems.
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.
