2-part polyurethane grout for continuous embedded tracks with medium axle loads Sika® Icosit® KC 340/45 is a flexible 2-part polyurethane polymer resin grout that can be applied manually or by machine. It is designed as a vibration absorbing, load-bearing, flexible grout for fixing grooved or T–rails onto concrete slabs, steel bridge decks and tunnel invert slabs. Particularly suitable for embedded (floating) rail designs.

Technical Information
Shore A Hardness
55 ± 5 (after 28 days) Shore hardness assists with material identification and assessing the curing progress on site.
Compressive stiffness
Load-Deflection Diagram* Static stiffness determined according to DIN 45673-1. Test specimen dimensions: 1,000 x 180 x 25 mm (pure material value measured without rail) Preload: 1,000 N Testing speed: 2 kN/s Maximum load: 50 kN Bedding figure kstat = ~102 [(kN/mm)/m] (±10 %)*, determined as per the secant method between 8 and 32 kN. *Deviation of the bedding figure and the curve are ±10%.
Tensile Strength
~1.7 N/mm2 (ISO 527)
Electrical Resistivity
~2.85 x 109 Ωm (DIN VDE 0100-610 and DIN IEC 93)
Service Temperature
-40 °C minimum / +80 °C maximum short term up to +150 °C
Chemical Resistance
Long-term Resistant Against: Temporary Resistant Against: Short-term or No Resistance Against: Contact Sika® Technical Services for specific information. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||
Application Information
Mixing Ratio
Part A : Part B = 100 : 10 (parts by weight)
Layer Thickness
Minimum: 15 mm Maximum: 60 mm
Product Temperature
Condition product parts before application preferably at ~+15 °C to assist with flow and curing speed
Ambient Air Temperature
+5 °C min. / +35 °C max.
Relative Air Humidity
90 % max.
Substrate Temperature
+5 °C min. / +35 °C max.
Substrate Moisture Content
Dry to matt damp
Pot Life
~10 minutes at +20 °C After this time, the mixture becomes unuseable. Higher temperatures will shorten potlife.
Curing Time
Curing Rate
Waiting Time / Overcoating
On primer or coating at +20 °C
