Sika® Icosit® KC 330/10
2-part polyurethane grout for heavy wheel load rail fixing (shore D 75)
Sika® Icosit® KC 330/10 is a flexible two-part polyurethane polymer resin grout. It is designed as a vibration absorbing, load-bearing, flexible grout for discrete or continuous trackwork baseplates where particularly high wheel loads are involved.
- Heavy axle load main line vehicles and loading cranes.
- Noise and vibration suppression.
- Reduces erosion of concrete under baseplate.
- More uniform load distribution into substructure.
- Watertight undersealing.
- Flexible and elastic (shore D 75).
- Damping and compressible.
- Good electrical insulation against stray currents.
- No stress peaks on anchor bolts.
- Good adhesion on various substrates.
- Levels out tolerances.
- Powerful, shear-resistant adhesive.
- Absorbs dynamic stresses and prolongs the life of concrete substructure.
- Long durability, less maintenance.
Usage
- As a noise and vibration reducing grout under discrete baseplates or continuous embedded rails for high wheel loads (e.g. for heavy cranes, container gantry cranes, working pits and other similar applications).
- As a flexible levelling layer for fixing heavy industrial machines to reduce vibration transmission.

SUBSTRATE QUALITY
- Substrate must be sound, free from oil, grease, loose and friable particles.
- Apply Sika® Icosit® KC 330/10 only on dry contact surfaces.
SUBSTRATE PREPARATION
- To improve adhesion, apply Icosit® KC 330 Primer as a primer on absorbent substrates (concrete).
Note: Refer to the individual Product Data Sheets for more information.
MIXING
Sika® Icosit® KC 330/10 is supplied in pre-weighed composite units consisting of Parts A + B. Part A must be stirred thoroughly before being mixed with part B.
The following mixing instructions must be carried out:
- Use an electric or pneumatic mixer with basket type stirrer or helical stirrer, diameter 120–140 mm, speed ~600–800 rpm.
- Mixing time ~60 to 80 seconds.
- Ensure material is mixed from the container walls and the base by the stirrer during mixing.
CLEANING OF TOOLS
Mixing and application tools must be cleaned at regular intervals and immediately after use with Sika® Thinner C. Hardened material can only be removed mechanically.
