Sika® Icosit® KC 340/7
2-part polyurethane grout under discrete baseplates of main-line tracks
Sika® Icosit® KC 340/7 is a flexible 2-part polyurethane polymer resin grout. It is designed as a vibration absorbing, load-bearing, flexible grout for the precision alignment of rails, turnouts/switches etc. Sika® Icosit® KC 340/7 is also used for fixing track components to rigid substrates such as concrete slabs, steel bridge decks and tunnel invert slabs.
- Heavy axle load vehicles.
- Noise & vibration suppression.
- Reduces erosion of concrete under baseplate.
- More uniform load distribution into substructure.
- Watertight undersealing.
- Flexible, elastic (shore A 75).
- 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.
