Application Instructions : Spread mixed material on repair area and work firmly into substrate to ensure maximum surface contact. Plastic Steel®
Devcon Putty A fully cures 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 Plastic Steel Putty A prior to application.
FOR VERTICAL SURFACE APPLICATIONS
Devcon Plastic Steel Putty A can be troweled up to ¼” thick without sagging.
FOR MAXIMUM PHYSICAL PROPERTIES
Cure at room temperature for 2.5 hours, then heat cure for 4 hours @ 200 Degress F.
FOR ± 70 Degrees F APPLICATIONS
Applying epoxy at temperatures below 70 Degrees F lengthens functional cure and pot life times. Conversely, applying above 70 Degrees F shortens functional cure and pot life.
MACHINING: Allow material to cure for at least 16 hours before machining.
Lathe speed: 150 ft/min
Cut: Dry
Tools: Carbide Top Rake 6° (+/-2°) – Side/Front 8°F (+/-2°)
Polishing: Use 400-650 grit emery paper wet. Material should polish to a 25-50 micro inch.
