Devcon Bronze Putty (BR)

Spread mixed material on repair area and work firmly into substrate to ensure maximum surface contact. Bronze Putty will fully cure Instructions: 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 Aluminum Putty (F) prior to application. FOR VERTICAL SURFACE APPLICATIONS Bronze Putty can be troweled up to ¼” (6.4 mm) thick without sagging. FOR MAXIMUM PHYSICAL PROPERTIES Cure at room temperature for 2.5 hours, then heat cure for 4 hours @ 200°F (93oC). FOR ± 70°F (21°C) APPLICATIONS Applying epoxy at temperatures below 70°F (21°C) lengthens functional cure and pot life times. Conversely, applying above 70°F (21oC) shortens functional cure and pot life. MACHINING: Allow material to cure for at least four hours before machining. – Lathe speed: 150 ft/min (46 m/min) – Cut: Dry – Tools: Carbide Top Rake 6° (+/-2°) – Side/Front 8°F (+/-2°) 14 C (+/-1), -13 C (+/- 1) – Feed Rate (rough): Travel speed 0.020 Rough cut 0.020 – 0.060 – Feed Rate (finishing): Travel speed 0.010 Finish cut 0.010 – Polishing: Use 400-650 grit emery paper wet. Material should polish to a 25-50 micro inch.
