Polyurethane

Part A: 7 months from date of production
Part B: 12 months from date of production

The packaging must be stored properly in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between +5°C and +30°C.

All density values at +23 °C

Resistant to many chemicals. Contact Sika Technical Services for specific information.

¹⁾ In accordance with IEC 61340-5-1 and ANSI/ESD S20.20.
²⁾ Readings may vary, depending on ambient conditions (i.e. temperature, humidity) and measurement equipment.
³⁾ Or < 10⁹ Ω + body voltage generation of < 100 V, in case of readings > 35 M Ω.

Part A : Part B + H₂O = 85 : 15 : 10 (by weight)

+10 °C minimum / +30 °C maximum

During curing, the humidity should not exceed a maximum level of 75 %. Adequate fresh air ventilation or a dehumidifier must be provided to remove the excess moisture from the curing product.

Beware of condensation. The substrate and uncured floor must be at least 3°C above the dew point to reduce the risk of condensation or blooming on the floor finish.

+10 °C minimum / +30 °C maximum

Caution: The end of the pot-life is not noticeable; the viscosity will increase only slightly!

Before overcoating Sikafloor®-305 W ESD allow:

Based on a maximum RH of 70 % and good ventilation. Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

Note: Times are approximate and will be affected by changing ambient conditions.

~0.18–0.20 kg/m²/layer

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage, etc. When used in high wear conditions, for example where rolling office chairs occur, a double layer Sikafloor®-305 W ESD is highly advisable, as a double layer is increasing the mechanical strength of the system and its resistance against office chair wheels particularly.

Lower consumption can cause roller marks, gloss differences and irregular surface structure, higher consumption result in water retention and can cause pigment floating as well as unsatisfactory conductivity.

Prior to mixing, stir Part A mechanically. When all of Part B has been added to Part A, mix continuously for 3 minutes until a uniform mix has been achieved. In order to achieve smoother surface 10 % water must be added. After adding the water, mix continuously for 1 minute. Wait 1 minute and then mix it up again for a further 1 minute. The addition of water must be the same in every mix; if not, it could slightly influence the mattness and the texture. To ensure thorough mixing, pour materials into another container and mix again to achieve a consistent mix.
Over-mixing must be avoided to minimise air entrainment.

       
Mixing Tools:
Sikafloor®-305 W ESD must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.

Prior to application, confirm relative air humidity and dew point.

The floor must be divided into sections (at expansion joints or doorways where possible) that can be completed without stopping. Short pile (12 - 13 mm) nylon roller and trays are preferred tools.

The application must be carried out in 3 steps:

One worker has the task of applying the material in the corners, around columns or other installations using an appropriate brush. He has to take care to always have a “wet” edge maintained during application.

The second worker is responsible for distributing the material crosswise by roller in the correct consumption. He also has to take care that a “wet” edge is always maintained during application.

The third worker, equipped with spiked shoes with blunt spikes, has to enter the freshly applied area. He has the task of the final distribution of the material by roller. This must be done always parallel to his movement, “out of the area”, in order to achieve a seamless finish.

It is mandatory to work evenly in order to avoid late re-rolling to adjacent, previously applied material which might be already dry. A seamless finish can be achieved if a “wet” edge is maintained during application.

Please refer to the Method Statement: “MIXING & APPLICATION OF FLOORING SYSTEMS”.

Clean all tools and application equipment with water immediately after use. Hardened and / or cured material can only be removed mechanically.
