PRODUCT DESCRIPTION
CHOCKFAST RED SG 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 with clearances as little
as 1” (25mm). CHOCKFAST RED SG has extremely high
physical properties and negligible shrinkage, making it
ideal for nal positioning of critically aligned equipment
within close tolerances. Skid mounted compressors,
extruders, turbines, pumps, motors and crane rails are
just a few types of equipment supported on CHOCKFAST
RED SG. When using CHOCKFAST RED SG for crane rail
applications expansion joints may be placed every 10’ (3m).
USE & BENEFITS
CHOCKFAST RED SG has the following advantages when
compared to conventional cementitious grouts:
• Impervious to oil and chemical attack
• Cures at least three times as quickly
• Pre-packaged unit
• Grout machinery in nal aligned position
• Higher physical strengths
• Strong bond to metal and concrete
• Unaffected by weathering and freeze/thaw cycling
• Superior resistance to fatigue
CHOCKFAST RED SG contains no non-reactive diluents
which could interfere with the curing mechanism or which
could cause material loss during or after cure.
Machinery may be positioned at its nal elevation before
pouring because the shrinkage is negligible. Critical
alignments are maintained during machinery operation
due to CHOCKFAST RED SG’s high dimensional stability
and resistance to creep and vibration.
DESIGN CONSIDERATIONS
For design considerations and application details, please
request Bulletin No. 643 or contact ITW Performance Poly-
mers Service Department.
APPLICATION INSTRUCTIONS
CHOCKFAST RED SG may be mixed with a contractor’s
hoe and wheelbarrow or in a portable mortar mixer.
Thoroughly mix hardener with resin rst before mixing
in aggregate. Where a very owable mix is required, the
aggregate content may be reduced accordingly.
Contact the CHOCKFAST Representative or ITW Perfor-
mance Polymers when reducing aggregate.
CHOCKFAST RED SG 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. CHOCKFAST
RED SG may be used in any thicknessgreater than 1”
(25mm); however, individual pours should generally not
exceed 4” (100mm) in thickness and 5’ (1.5m) in length.
CHOCKFAST RED SG cure rates and owability will be
enhanced somewhat if material temperatures are warmer
than the existing ambient conditions listed above.
It is always a good idea to keep CHOCKFAST RED SG
materials in a well-protected area until the job site is fully
prepared for mixing and placement.
NOTE: Standard CHOCKFAST RED is available and allows
deep single pours to 18” (450mm) for concrete reconstructi-
on. Please see Bulletins No. 642 and 617.
