Bronze Putty

Description: Bronze-filled epoxy for repairing, rebuilding, and maintaining bronze parts and equipment
Intended Use: Repair, rebuild, and maintain marine propellers, shafts, trays, chutes, gate valves, and pump wear rings
Product  Resistant to chemicals and most acids, bases, solvents, and alkalis
features: Machinable to metallic finish
Bonds to ferrous and non-ferrous metals
Application  Spread mixed material on repair area and work firmly into substrate to ensure maximum surface contact. Bronze Putty will
Instructions: fully cure in 16 hours, at which time it can be machined, drilled, or painted.
FOR BRIDGING LARGE GAPS OR HOLES
Place fiberglass sheet, expanded metal, or mechanical fasteners between repair area and Bronze Putty prior to
application.
FOR VERTICAL SURFACE APPLICATIONS
Bronze Putty can be troweled up to 1/4” thick without sagging.
FOR MAXIMUM PHYSICAL PROPERTIES
Cure at room temperature for 2.5 hours, then heat cure for 4 hours @ 200°F.
FOR ± 70°F APPLICATIONS
Applying epoxy at temperatures below 70°F lengthens functional cure and pot life times. Conversely, applying above 70°F
shortens functional cure and pot life.
MACHINING:
Allow material to cure for at least four hours before machining.
