Refer to the chemical resistance of Sikafloor®-2350 ESD.
Temperature Resistance
| Short-term, maximum 7 days | +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 chemical and/or mechanical strain, as it may cause damage to the product.
Electrostatic Behaviour
| Resistance to ground | RG < 109 Ω |
| Typical average resistance to ground | RG ≤ 105 Ω to 106 Ω |
| Body voltage generation | < 100 V |
| System Resistance (Per-son/Floor/footwear) | < 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.
ESD 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 fol-lowing 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/50 % |
| 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) |
| Measuring device for measuring body voltage generation | Walking Test Kit WT 5000 (Warm-bier) or comparable |
Application
Ambient Air Temperature
| Minimum | +15 °C |
| Maximum | +30 °C |
Relative Air Humidity
80 % r.h. max.
Dew Point
Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.
Substrate Temperature
| Minimum | +15 °C |
| Maximum | +30 °C |
Substrate Moisture Content
< 4 % parts by weight (Sika® Tramex moisture meter)
No rising moisture (ASTM D4263, polyethylene sheet)
The substrate must be visibly dry with no standing water.
Waiting Time / Overcoating
Before applying Sikafloor®-220 W Conductive on Sikafloor®-161 HC allow:
| Substrate temperature | Minimum | Maximum |
| +15 °C | ~24 hours | ~4 days |
| +20 °C | ~12 hours | ~48 hours |
| +30 °C | ~8 hours | ~24 hours |
Before applying Sikafloor®-2350 ESD on Sikafloor®-220 W Conductive allow:
| Substrate 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 |

Consumption
Self smoothing / resin screed
| Layer | Product | Consumption |
| Primer or scratch coat | 1–2 × Sikafloor®-161 HC | ~0.3 kg/m² to 0.5 kg/m² |
| Levelling (if required) | Sikafloor®-161 HC | Refer to the individual Product Data Sheet |
| Conductive Primer + Earthing connection | Sikafloor®-220 W Conductive + Sika® Earthing Kit | 1 × 0.08–0.10 kg/m² |
| Wearing layer / Wear-ing screed | Sikafloor®-2350 ESD filled with 20% quartz sand 0.1-0.3 mm | Maximum 2.5 kg/m² |
APPLICATION
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.
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 de-scribed above, until the fulfilment of the requirements have been verified. If the requirements cannot be verified, contact Sika technical services.
