Sika Sikaflow 668 Kit 0.47cf
Sika Sikaflow-668 is a three-component modified epoxy resin-based chock grout designed for high-performance equipment mounting in less-accessible spaces subject to thermal shock and high vibration. This highly flowable epoxy chock grout conforms to worn or irregular surfaces and can be used where conventional epoxy grouts are not practical. Sikaflow-668 is intended for precision machinery grouting, steel-to-steel chock grouting, and demanding applications such as compressors and turbines.
Key Features
- Three-component modified epoxy resin-based chock grout.
- Highly flowable to conform to worn or irregular surfaces.
- Designed for high-performance properties in thermal shock and high-vibration environments.
- May replace metal chocks to help eliminate costly milling.
- Low creep over a wide temperature range helps minimize deformation under sustained loads.
- Excellent physical properties across a wide temperature range.
- Suitable for limited-access spaces where conventional epoxy grouts cannot be used.
- Can be placed directly to concrete, on a base grout pour, or steel to steel.
Applications
- Precision grouting of machinery.
- Grouting of reciprocating gas compressors.
- Grouting of steam turbines.
- Grouting of gas turbines.
- Steel-to-steel chock grouting.
- Equipment mounting in limited-access spaces.
- Applications requiring epoxy chocks on a base grout pour.
- High-vibration industrial mounting applications.

FAQs
What is Sika Sikaflow-668 used for?
It is used for precision machinery grouting, reciprocating gas compressors, steam and gas turbines, and steel-to-steel chock grouting where high performance is required.
What makes Sikaflow-668 different from conventional epoxy grouts?
It is designed for less-accessible spaces and highly demanding service conditions involving thermal shock and high vibration, where conventional epoxy grouts may not be suitable.
Can Sikaflow-668 replace metal chocks?
Yes. The data sheet states that it may be used to replace metal chocks, helping eliminate costly milling.
What thickness can Sikaflow-668 be placed at?
It can be placed from 1/2 inch to 3 inches thick on a base grout pour, directly to concrete, or steel to steel.
Can solvent or extra water be added to the mix?
No. The data sheet specifically states not to add solvent, water, or any other material and not to alter the resin or hardener proportions.
How should Sikaflow-668 be mixed?
Part B hardener is poured into Part A resin and mixed to a uniform amber color, then combined with Part C aggregate in a horizontal shaft mortar mixer or Kol type mixer until the aggregate is completely wetted out.
