~100 % by volume

~100 % by weight

Water, see water, sewage water, thinned anorganic acids and bases, salt, detergents, grease, oil and short term resistant to motor fuel and solvents.

Dry heat up to + 100°C, short term up to approx. + 250°C

Max. 85 %, expect the surface temperature is significantly higher than the dew point temperature, it shall be at least 3 K above dew point.

Between SikaCor® HM Primer Plus and SikaCor® Elastomastic TFN:
Min. 1 day, max. 1 month. Prime once again with 1 x SikaCor® HM Primer Plus in case of longer waiting time.

Between 1^st and 2^nd layer of SikaCor® Elastomastic TFN:
Min.1 day, max. 1 month

Between SikaCor® Elastomastic TFN and SikaCor® EG-5 or Sikafloor®-359 N
Min. 1 day, max. 1 month

Between 1^st and 2^nd layer of Sikafloor®-150:
Min.12 hours, max. 2 days

Between Sikafloor®-150 and SikaCor® Elastomastic TFN:
Min. 12 hours at + 20°C, max. 2 days

Prior to application of the next layer a thorough dedusting is necessary.
If the waiting time between the layers of SikaCor® Elastomastic TFN will be longer as mentioned above, than the coating has to be prepared by sweep blasting before applying SikaCor® Elastomastic TFN again.

Final drying time
Fully cured after 7 days at + 20°C.
Ballast can be placed after 3 days.

For road surface and side walk according to ZTV-ING, part 7, chapter 5:

*1) If application temperatures are lower than +15°C the addition of
       aggregate can be reduced down to a ratio of 1 : 0.7.

*2) 2 layer system: The aggregate for filling the 1^st and 2^nd layer and for
       broadcasting the 1^st layer (not in excess) is quartz sand 0.4-0.7 mm.
       The 2^nd layer has to be broadcasted with quartz sand 0.7-1.2 mm.

*3) 2 layer system: The aggregate for filling the 1^st and 2^nd layer and for
       broadcasting the 1^st layer (not in excess) is DUROP 1/2.
       The 2^nd layer has to be broadcasted with DUROP 2/3.

Before applying the 2^nd layer the non-adherent bonded quartz sand resp. DUROP has to be brushed off.

For slope surfaces 0.5-1.5 % by weight Extender T (related to ready mixed material) must be added to prevent sagging; the dosage depends on the ambient and material temperature.

For ballast troughs according to DBS 918084 (German Railway):

SikaCor® Elastomastic TFN not filled with quartz sand:

Optional 1 x SikaCor® HM Primer Plus, dry film thickness 80 μm

Horizontal surfaces: Layer thickness 4 mm.
Apply SikaCor® Elastomastic TFN in 3 mm, consumption

approx. 3.9 kg/m².

Broadcasting with quartz sand 0.4-0.7 mm in excess (8-10 kg/m²).

Vertical surfaces: Layer thickness 2 mm.
Apply SikaCor® Elastomastic TFN in two layers, 1 mm each by adding

2-3 % b.w. Extender T, consumption approx. 1.3 kg/m² per layer.

Broadcasting with quartz sand 0.4-0.7 mm after each layer.

SikaCor® Elastomastic TFN, filled with quartz sand:

Optional 1 x SikaCor® HM Primer Plus, dry film thickness 80 μm

Horizontal surfaces: Layer thickness 4 mm.

Apply SikaCor® Elastomastic TFN, 1:1 filled with quartz sand 0.4-0.7 mm in 4 mm. Consumption of binder and quartz sand each approx. 3.0 kg/m².

Broadcasting with quartz sand 0.4-0.7 mm in excess (6 kg/m²).

Vertical surfaces: Layer thickness 2 mm.
Apply SikaCor® Elastomastic TFN, 1:1 filled with quartz sand 0.4-0.7 mm in two layers, 1 mm each by adding 2-3 % b.w. Extender T.

Consumption of binder and quartz sand each approx. 0.75 kg/m² per layer.

Broadcasting with quartz sand 0.4-0.7 mm after each layer.

For concrete surfaces:
 

Concrete:

• Concrete substrates must be structurally sound and of sufficient compressive strength (min. 25 N/mm²) with a minimum pull off strength of 1.5 N/mm².
• The substrate must be clean, dry and free of all contaminants such as dirt, dust, oil, grease, coatings, laitance and loose friable material.
• Concrete substrates and PCC mortars must be prepared mechanically using suitable abrasive blast-cleaning or scarifying equipment to remove cement laitance and achieve an open textured gripping surface profile.
• Moisture content of substrate < 4 % b.w.

Stir component A very thoroughly using an electric mixer (start slowly, then increase up to approx. 300 rpm). Add component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into clean container, add the aggregates if necessary and mix again shortly as described above. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothings.

Apply SikaCor® Elastomastic TFN by using a trowel, kaupp trowel, squeegee, serrated trowel or similar.
Overroll the freshly applied layer with a spike roller and broadcast with quartz sand approx. 15 minutes after application (at + 20°C).
