Sika® Icosit® KC 340/4
2-part polyurethane grout under discrete baseplates of tram / light rail tracks
Sika® Icosit® KC 340/4 is a flexible two-part polymer grout based on polyurethane resin. It is designed as a vibration absorbing, load-bearing, flexible grout for the precision alignment of rails, turnouts / switches, etc. Sika® Icosit® KC 340/4 is also used for fixing track components to rigid substrates such as concrete slabs, steel bridge decks and tunnel invert slabs.
- Medium axle loads of trams and light-rail vehicles.
- Noise and vibration suppression.
- Reduces erosion of concrete under baseplate.
- More uniform load distribution into substructure.
- Watertight undersealing.
- Flexible, elastic (shore A 65).
- Damping, compressible.
- Good electrical insulation against stray currents.
- No stress peaks on anchor bolts.
- Excellent adhesion on various substrates.
- Levels out tolerances.
- Suitable as a powerful, shear-resistant adhesive.
- Absorbs dynamic stresses and prolongs the life of concrete substructure.
- Insensitive to moisture.
- Long durability, less maintenance.
