Metalink Machinable Repair Compound is a trowelable stainless steel filled polymer compound for repairing and rebuilding parts and surfaces. Once hardened, it can be drilled, tapped, sanded, machined and painted just like metal. ML400 will bond to steel, cast iron, stainless steel, all ferrous and non-ferrous metals, concrete, glass, and wood. The stainless steel filler provides maximum durability and performance. The new, improved formula provides a smooth, silk finish with extreme abrasion and corrosion resistance.

APPLICATION INSTRUCTIONS:
- Grind, sand, brush or grit-blast surface for best adhesion. Clean with CH020N Metal Prep II Degreaser and wipe dry. In humid climates it is advisable to flame brush the surface to prevent flash rusting. This will also help the polymer “wet out” on the surface.
- Mix 3 parts Resin to 1 part Hardener, or mix the entire unit. Mix thoroughly until uniform in color (no streaks). Apply fully mixed material to desired surface.
- Working time is 30 minutes at room temperature. Material is hard in 3 to 4 hours. The curing time may be shortened considerably by heating the surface to 150ºF.
TYPICAL APPLICATIONS:
- Repairing Scored Shafts and Hydraulic Rams
- Refitting Worn Keyways and Spline Shafts
- Reseating Bearing Housings
- Rebuilding Armature Castings
- Reforming Stripped Threads
- Cuts on Flanges and Gasket Surfaces
- Leaks in Pipes and Castings
- Remetalizing Shafts and Sleeves
- Rebuilding Impellers and other Pump Parts
- Rebuilding Valve Seats
- Lining Pitted and Worn Pump and Valve
- Casings and Elbows
