CHOCKFAST RED

NO. 617N

CHOCKFAST RED is a three-component, high strength, 100% solids, epoxy grouting compound, which is used to grout large machinery and to support soleplates in all types of foundation designs. CHOCKFAST RED has extremely high compressive strength and negligible shrinkage, making it ideal for the final positioning of critically aligned machinery within close tolerances.

CHOCKFAST RED has the following advantages when compared to conventional cement grouts:

CHOCKFAST RED contains no nonreactive diluents which could interfere with the curing mechanism or which could cause material loss during or after cure. Machinery may be positioned at its final elevation before pouring because the shrinkage is negligible. Critical alignments are maintained during machinery operation due to its high dimensional stability and resistance to creep and vibration.

CHOCKFAST RED may be mixed with contractor's hoe and wheelbarrow or in a small portable mortar mixer. Precondition resin, hardener and aggreate to 18-27C (65-80F) 48 hrs. before mixing. Thoroughly mix hardener with resin first before mixing in aggregate. Where a very flowable mix is required the aggregate content may be reduced accordingly. However, in loadbearing areas a maximum reduction to 3-1/2 bags is recommended. Please contact the CHOCKFAST Representative or lTW Philadelphia Resins if less than 3-1/2 bags are being considered. See Bulletin No. 642 for mixing procedures.

CHOCKFAST RED is quick curing, relative to cement grouts, but the cure is thermally gentle. This allows thick pours to be made without causing the stress cracks often associated with a hot-curing epoxy grout. CHQCKFAST RED may be used in thickness greater than 30mm (1.25"), however, individual pours should generally not exceed 46cm (18") in thickness and 2.2m (7') in length. When grouting highly critically aligned machinery which is coupled to another machine it is advisable to limit the final leveling pour in accordance with the instructions in Bulletin No. 615 (latest revision).

For design considerations and application details please request Bulletin No. 642 or contact ITW Philadelphia Resins' Engineering Services Department.
