TUFFALLOY 4200 Series

Available in (4) speeds:

• 15 minute working life 6 hour demold

• 7 minute working life   2 hour demold

• 2 minute working life   4-6 minute demold with heated molds,   8-20 minutes at room temperature

• 1 minute working life   3-4 minute demold with heated molds,   4-10 minute demold at room temperature

• The user has the ability to use different speeds, typically using a slower speed initially, and increasing to a fast set, 1 minute working life.

• The switch or interchangeability of TUFFALLOY  materials is easily done without any changes in physical properties.

PROCESSING:

• TUFFALLOY can be pressure cast, vacuum cast, or open cast.

• For best results, TUFFALLOY 4274/5 and 4284/5 should be used with Hapco's metering/dispensing equipment, RAPIDFIL and/or RAPIDSHOT.

TUFFALLOY 5030 has a short cycle time, providing a high volume of parts per day.
