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
This product fulfils the re-quirements of ATEX 137

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.

Application

Application Information

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.

Application steps

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:

  1. 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.
