UsageHigh quality coating e.g. for bridge decks, inspection sidewalks, pavements and bicycle tracks, traffic areas, railway bridges, curbs and inside of ballast troughs. For application of thick-layer, wear-resistant, highly mechanically resistant and at the same time chemically resistant corrosion protection system. For levelling resp. producing slope surfaces to avoid standing water puddles. Advantages▪ High performance corrosion protection ▪ Mechanical, tough elastic- and impact resistant ▪ Very good adhesion on steel and concrete substrates Packaging

ApplicationMixing ratio
Material temperature
Relative air humidity Max. 85 %, expect the surface temperature is significantly higher than the dew point temperature, it shall be at least 3 K above dew point. Pot Life
Waiting time to overcoating 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 (+ 68 °F), 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. Drying time
Final drying time Fully cured after 7 days at + 20°C (+ 68 °F). Ballast can be placed after 3 days. Surface temperature
Consumption For road surface and side walk according to ZTV-ING, part 7, chapter 5:
*1) If application temperatures are lower than +15°C (+59 °F) 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 (0.0157-0.0276 in). The 2 nd layer has to be broadcasted with quartz sand 0.7-1.2 mm (0.0276-0.0472 in). *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. *4) Source of DDUROP: KORODUR Westphal Hartbeton GmbH & Co.KG info@korodur.de / www.korodur.de 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 (0.157 in). Apply SikaCor® Elastomastic TFN in 3 mm (0.118 in), consumption approx. 3.9 kg/m 2 . Broadcasting with quartz sand 0.4-0.7 mm (0.0157-0.0276 in) in excess (8-10 kg/m 2 ). Vertical surfaces: Layer thickness 2 mm (0.0787 in). Apply SikaCor® Elastomastic TFN in two layers, 1 mm (0.0394 in) each by adding 2-3 % b.w. Extender T, consumption approx. 1.3 kg/m 2 per layer. Broadcasting with quartz sand 0.4-0.7 mm (0.0157-0.0276 in) 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 (0.157 in). Apply SikaCor® Elastomastic TFN, 1:1 filled with quartz sand 0.4-0.7 mm (0.0157-0.0276 in) in 4 mm (0.157 in). Consumption of binder and quartz sand each approx. 3.0 kg/m 2 . Broadcasting with quartz sand 0.4-0.7 mm (0.0157-0.0276 in) in excess (6 kg/m 2 ). Vertical surfaces: Layer thickness 2 mm (0.0787 in). Apply SikaCor® Elastomastic TFN, 1:1 filled with quartz sand 0.4-0.7 mm (0.0157-0.0276 in) in two layers, 1 mm (0.0394 in) each by adding 2-3 % b.w. Extender T. Consumption of binder and quartz sand each approx. 0.75 kg/m 2 per layer. Broadcasting with quartz sand 0.4-0.7 mm (0.0157-0.0276 in) after each layer. For concrete surfaces:
SUBSTRATE PREPARATION Concrete:
MIXING 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. APPLICATION 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 (+ 68 °F)). Do not thin SikaCor® Elastomastic TFN!
