Master Flow 400 Epoxy Grouting System | MCT CHEMICALS | MASTER BUILDER SOLUTIONS

USES
MasterFlow 400 is intended for use by experienced professionals only. It is ideal for high-strength grouting and fixing of:

• Starter bars
• Anchors
• Fasteners
• Tie rods
• Crash barrier posts
• Fence and railing posts

It is also used for under-grouting and bedding of:

• Base plates
• Machine bases and seat base-plates for both light and heavy machinery, including machinery subject to heavy impact and vibration (e.g., reciprocating engines, compressors, pumps, presses)
• Bridge bearings
• Mechanical joints (e.g., road/bridge/deck types)

Additionally, it is suitable for sleeperless, direct rail fixing of:

• Crane tracks
• Light rail and permanent way in tunnels
• Light rail and permanent way over bridges
